A tree is a tall plant with a trunk and branches made of wood. Trees can live for many years. The oldest tree ever discovered is approximately 5,000 years old. The four main parts of a tree are the roots, the trunk, the branches, and the leaves.
The roots of a tree are usually under the ground. One case for which this is not true are the roots of the mangrove tree which are often under water. A single tree has many roots. The roots carry food and water from the ground through the trunk and branches to the leaves of the tree. They can also breathe in air. Sometimes, roots are specialized into aerial roots, which can also provide support, as is the case with the banyan tree.
The trunk is the main body of the tree. The trunk is covered with bark which protects it from damage. Branches grow from the trunk. They spread out so that the leaves can get more sunlight.
The leaves of a tree are green most of the time, but they can come in many colours, shapes and sizes. The leaves take in sunlight and use water and food from the roots to make the tree grow, and to reproduce.
Trees and shrubs take in water and carbon dioxide and give out oxygen with sunlight to form sugars. This is the opposite of what animals do in respiration. Plants also do some respiration using oxygen the way animals do. They need oxygen as well as carbon dioxide to live.
Parts of trees[change | change source]
The parts of a tree are the roots, trunk(s), branches, twigs and leaves. Tree stems are mainly made of support and transport tissues (xylem and phloem). Wood consists of xylem cells, and bark is made of phloem and other tissues external to the vascular cambium.
Growth of the trunk[change | change source]
As a tree grows, it may produce growth rings as new wood is laid down around the old wood. In areas with seasonal climate, wood produced at different times of the year may alternate light and dark rings. In temperate climates, and tropical climates with a single wet-dry season alternation, the growth rings are annual, each pair of light and dark rings being one year of growth. In areas with two wet and dry seasons each year, there may be two pairs of light and dark rings each year; and in some (mainly semi-desert regions with irregular rainfall), there may be a new growth ring with each rainfall.
In tropical rainforest regions, with constant year-round climate, growth is continuous. Growth rings are not visible and there is no change in the wood texture. In species with annual rings, these rings can be counted to find the age of the tree. This way, wood taken from trees in the past can be dated, because the patterns of ring thickness are very distinctive. This is dendrochronology. Very few tropical trees can be accurately dated in this manner.
Roots[change | change source]
The roots of a tree are generally down in earth, providing anchorage for the parts above ground, and taking in water and nutrients from the soil. Most trees need help from a fungus for better uptake of nutriens: this is mycorrhiza. Most of a tree's biomass comes from carbon dioxide absorbed from the atmosphere (see photosynthesis). Above ground, the trunk gives height to the leaf-bearing branches, competing with other plant species for sunlight. In many trees, the order of the branches makes exposure of the leaves to sunlight better.
Exceptions[change | change source]
Not all trees have all the organs or parts as mentioned above. For example, most palm trees are not branched, the saguaro cactus of North America has no functional leaves, tree ferns do not produce bark, etc. Based on their general shape and size, all of these are nonetheless generally regarded as trees. Trees can vary very much. A plant form that is similar to a tree, but generally having smaller, multiple trunks and/or branches that arise near the ground, is called a shrub (or a bush). Even though that is true, no precise differentiation between shrubs and trees is possible. Given their small size, bonsai plants would not technically be 'trees', but one should not confuse reference to the form of a species with the size or shape of individual specimens. A spruce seedling does not fit the definition of a tree, but all spruces are trees.
Classification[change | change source]
A tree is a plant form that can be found in many different orders and families of plants. Trees show many growth forms, leaf type and shape, bark traits and organs.
The tree form has changed separately in classes of plants that are not related, in response to similar problems (for the tree). With about 100,000 types of trees, the number of tree types in the whole world might be one fourth of all living plant types. Most tree species grow in tropical parts of the world and many of these areas have not been surveyed yet by botanists (they study plants), making species difference and ranges not well understood.
The earliest trees were tree ferns, horsetails and lycophytes, which grew in forests in the Carboniferous period; tree ferns still survive, but the only surviving horsetails and lycophytes are not of tree form. Later, in the Triassic Period, conifers, ginkgos, cycads and other gymnosperms appeared, and subsequently flowering plants in the Cretaceous period. Most species of trees today are flowering plants (Angiosperms) and conifers.
A small group of trees growing together is called a grove or copse, and a landscape covered by a dense growth of trees is called a forest. Several biotopes are defined largely by the trees that inhabit them; examples are rainforest and taiga (see ecozones). A landscape of trees scattered or spaced across grassland (usually grazed or burned over periodically) is called a savanna. A forest of great age is called old growth forest or ancient woodland (in the UK). A very young tree is called a sapling.
Records[change | change source]
Height[change | change source]
The coast redwood: 115.85 metres (380.1 feet), in Redwood National Park, California is believed to be the world's tallest tree.
The tallest trees in Australia are all eucalypts, of which there are more than 700 species. The so-called 'mountain ash'. with a slim, straight trunk, grows to over 300 feet.
Stoutest trees[change | change source]
The stoutest living single-trunk species in diameter is the African baobab: 15.9 m (52 ft), Glencoe baobab (measured near the ground), Limpopo Province, South Africa. This tree split up in November 2009 and now the stoutest baobab could be Sunland Baobab (South Africa) with diameter 10.64 m and circumference of 33.4 m.
Some trees develop multiple trunks (whether from an individual tree or multiple trees) which grow together. The sacred fig is a notable example of this, forming additional 'trunks' by growing adventitious roots down from the branches, which then thicken up when the root reaches the ground to form new trunks; a single sacred fig tree can have hundreds of such trunks.
Age of trees[change | change source]
The life-span of trees is determined by growth rings. These can be seen if the tree is cut down or in cores taken from the edge to the center of the tree. Correct determination is only possible for trees which make growth rings, generally those which occur in seasonal climates. Trees in uniform non-seasonal tropical climates are always growing and do not have distinct growth rings. It is also only possible for trees which are solid to the center of the tree; many very old trees become hollow as the dead heartwood decays away. For some of these species, age estimates have been made on the basis of extrapolating current growth rates, but the results are usually little better than guesses or speculation. White proposed a method of estimating the age of large and veteran trees in the United Kingdom by correlation between a tree's stem diameter, growth character and age.
The verified oldest measured ages are:
- Great Basin bristlecone pine (Methuselah) Pinus longaeva: 4,844 years
- Alerce: 3,622 years
- Giant sequoia: 3,266 years
- Sugi: 3,000 years
- Huon-pine: 2,500 years
Other species suspected of reaching exceptional age include European Yew Taxus baccata (probably over 2,000 years) and western redcedar Thuja plicata. The oldest known European yew is the Llangernyw yew in the Churchyard of Llangernyw village in North Wales which is estimated to be between 4,000 and 5,000 years old.
The oldest reported age for an angiosperm tree is 2293 years for the Sri Maha Bodhisacred fig (Ficus religiosa) planted in 288 BC at Anuradhapura, Sri Lanka; this is said to be the oldest human-planted tree with a known planting date.
Tree value estimation[change | change source]
Studies have shown that trees contribute as much as 27% of the appraised land value in certain markets.
These most likely use diameter measured at breast height (dbh), 4.5 feet (140 cm) above ground—not the larger base diameter. A general model for any year and diameter is:
assuming 2.2% inflation per year.
Tree climbing[change | change source]
Tree climbing is an activity where one moves around in the crown of trees.
Use of a rope, helmet, and harness are the minimum requirements to ensure the safety of the climber. Other equipment can also be used depending on the experience and skill of the tree climber. Some tree climbers take special hammocks called "Treeboats" and Portaledges with them into the tree canopies where they can enjoy a picnic or nap, or spend the night.
Tree climbing is an "on rope" activity that puts together many different tricks and gear originally derived from rock climbing and caving. These techniques are used to climb trees for many purposes, including tree care (arborists), animal rescue, recreation, sport, research, and activism.
Damage[change | change source]
The three big sources of tree damage are biotic (from living sources), abiotic (from non-living sources) and deforestation (cutting trees down). Biotic sources would include insects which might bore into the tree, deer which might rub bark off the trunk, or fungi, which might attach themselves to the tree.
Abiotic sources include lightning, vehicles impacts, and construction activities. Construction activities can involve a number of damage sources, including grade changes that prevent aeration to roots, spills involving toxic chemicals such as cement or petroleum products, or severing of branches or roots. People can damage trees also.
Both damage sources can result in trees becoming dangerous, and the term "hazard trees" is commonly used by arborists, and industry groups such as power line operators. Hazard trees are trees which due to disease or other factors are more susceptible to falling during windstorms, or having parts of the tree fall.
The process of finding the danger a tree presents is based on a process called the quantified tree risk assessment.
Trees are similar to people. Both can take a lot of some types of damage and survive, but even small amounts of certain types of trauma can result in death. Arborists are very aware that established trees will not tolerate any appreciable disturbance of the root system. Even though that is true, most people and construction professionals do not realize how easily a tree can be killed.
One reason for confusion about tree damage from construction involves the dormancy of trees during winter. Another factor is that trees may not show symptoms of damage until 24 months or longer after damage has occurred. For that reason, persons who do not know about caring for trees may not link the actual cause with the later damaged effect.
Various organizations have long recognized the importance of construction activities that impact tree health. The impacts are important because they can result in monetary losses due to tree damage and resultant remediation or replacement costs, as well as violation of government ordinances or community or subdivision restrictions.
As a result, protocols (standard ways) for tree management prior to, during and after construction activities are well established, tested and refined (changed). These basic steps are involved:
- Review of the construction plans
- Development of the related tree inventory
- Application of standard construction tree management protocols
- Assessment of potential for expected tree damages
- Development of a tree protection plan (providing for pre-, concurrent, and post construction damage prevention and remediation steps)
- Development of a tree protection plan
- Development of a remediation plan
- Implementation of tree protection zones (TPZs)
- Assessment of construction tree damage, post-construction
- Implementation of the remediation plan
Trees in culture[change | change source]
The tree has always been a cultural symbol. Common icons are the World tree, for instance Yggdrasil, and the tree of life. The tree is often used to represent nature or the environment itself. A common mistake (wrong thing) is that trees get most of their mass from the ground. In fact, 99% of a tree's mass comes from the air.
Wishing trees[change | change source]
A Wish Tree (or wishing tree) is a single tree, usually distinguished by species, position or appearance, which is used as an object of wishes and offerings. Such trees are identified as possessing a special religious or spiritual value. By tradition, believers make votive offerings in order to gain from that nature spirit, saint or goddess fulfillment of a wish.
Tree worship[change | change source]
Tree worship refers to the tendency of many societies in all of history to worship or otherwise mythologize trees. Trees have played a very important role in many of the world's mythologies and religions, and have been given deep and sacred meanings throughout the ages. Human beings, seeing the growth and death of trees, the elasticity of their branches, the sensitiveness and the annual (every year) decay and revival of their foliage, see them as powerful symbols of growth, decay and resurrection. The most ancient cross-cultural symbolic representation of the universe's construction is the 'world tree'.
World tree[change | change source]
The tree, with its branches reaching up into the sky, and roots deep into the earth, can be seen to dwell in three worlds - a link between heaven, the earth, and the underworld, uniting above and below. It is also both a feminine symbol, bearing sustenance; and a masculine, phallic symbol - another union.
For this reason, many mythologies around the world have the concept of the World tree, a great tree that acts as an Axis mundi, holding up the cosmos, and providing a link between the heavens, earth and underworld. In European mythology the best known example is the tree Yggdrasil from Norse mythology.
The world tree is also an important part of Mesoamerican mythologies, where it represents the four cardinal directions (north, south, east, and west). The concept of the world tree is also closely linked to the motif of the Tree of life.
In literature[change | change source]
In literature, a mythology was notably developed by J.R.R. Tolkien, his Two Trees of Valinor playing a central role in his 1964 Tree and Leaf. William Butler Yeats describes a "holy tree" in his poem The Two Trees (1893).

Essay on Save Trees
Trees are as much important to our life as food and water. Life becomes very difficult without trees or we can say that life would be finished because trees are most important aspect of giving us healthy and wealthy life. Save trees is the important social awareness now-a-days and have been included in the student’s life through the study. Students are generally assigned this topic to discuss or write short or long essay in their exams or any quiz competition in their school. We have provided variety of short and long essay on save trees under different words limit to help school students. You can select any save trees essay according to the need:
Save Trees Essay 1 (100 words)
Trees give us life directly and indirectly as they are source of oxygen production, CO2 consumption and source of rain. They are most precious gift to the humanity on the earth from nature for which we must be grateful, give honour and preserve for the mankind wellness.
We should understood importance of trees in our lives and do our best to save trees in order to save life, save environment on the earth and make earth a green earth. Trees are as valuable as gold that’s why they are called as “Green Gold” on the earth. They are the real source of our health as well as wealth because they give us oxygen, cool air, fruits, spices, vegetables, medicines, water, wood, furniture, shadow, fuel to burn, houses, fodder to animals and other useful things. They consume all the CO2, refresh air from toxic gases and prevent us from the air pollution.
Save Trees Essay 2 (150 words)
Trees gives us life and really very important for the survival on the earth. Many people are dependent on the tree for their survival economically for example paper industries, rubber industries, match industries, etc are totally dependent on trees. The main role of trees is giving fresh and oxygenated air to us and consumption of CO2 however they also give protection, shadow, food, source of money, home, medicines, etc to the people.
Trees are the source of rain on the earth as they attract clouds which ultimately bring rain. They also help in checking soil erosion and keep environment fresh by preventing from pollution. They are the home of wild animals and source of wild life in forests. Trees are very helpful and useful friends of humanity. They clean soil by filtering sewage and chemicals, control noise pollution, air pollution, reduce flash flooding, etc. By seeing the importance and value of trees in our life, we should honour and save trees in order to save life and environment.
Save Trees Essay 3 (200 words)
Trees are precious gift to our life from the nature. They are the green gold on the earth and very important for everyone’s life. Some of the importance of trees is mentioned below proving why save trees is save life:
- Trees are very important source of cleaning and refreshing air (as they produce oxygen and consume green house gases) by filtering and intercepting the airborne particles, chemicals, toxic gases, reducing heat, absorbing CO2 and other pollutants like sulphur dioxide, and nitrogen dioxide.
- Trees acts as natural dustbins to the harmful gases in the environment.
- Trees are source of natural shadow and cool air and most comfortable than the artificial cooling technologies like fan, coolers, air conditioning, etc.
- They are effective in breaking the force of wind thus helpful in protecting houses, vegetation, farmland, etc.
- They keep us healthy by lowering the dust levels and pollution levels especially in the urban areas.
- They prevent us from the respiratory disorders and breathing problems by refreshing air.
- They help in reducing noise pollution and most effective as sound barriers because they act most effectively like stone walls in stopping sound. They prevent us from the noises of crowded roads, railway stations, airports, etc.
- They prevent soil from erosion, helpful in rainwater conservation, and prevent sediment deposit during storms.
Save Trees Essay 4 (250 words)
Save trees, save life is not only a slogan, it is a responsibility which should be followed by each and every person living on the earth. It is a big opportunity to all of us to save our healthy environment and green earth by saving trees. Trees are symbol of life on the earth and natural home for many people and wild animals. Saving trees have been must at any cost in such a modern world where urbanization, industrialization and global warming is going very fast. In such a technological world, where people are fighting and working for themselves only, only trees are living for benefiting others (human beings and animals).
Trees are nourishing life on the earth in many ways by providing fruits, vegetables, foliage, flowers, spices, cool shade, medicines, roots, bark, wood, sprouts, etc. One fully grown tree may serve humanity for many years without getting anything in return. They prevent us from many diseases by purifying the air, maintaining the ecological balance, providing medicines, etc. Plants are like important assets prevent soil erosion, provide habitats to the faunal species, provide nutrients to soil etc. I have mentioned following ways to save trees and environment:
- We should make some effective efforts from our own end by joining the organizations working for save trees.
- We should make our trees saving service volunteer so that other people may also motivate.
- We should encourage our family members, friends, neighbors, small kids to get involve in saving our important resources.
- We should participate in the discussion or meeting related to the trees conservation issues in the community or state.
- We should hugely involve our new generation and teach children to respect trees, nature and environment by getting them to the hikes or camping.
- We should promote new planting in our surroundings.
Save Trees Essay 5 (300 words)
We are really bestowed by our mother earth many precious gifts nourishing our lives. One of the important precious gifts is trees. It is the source of food and shelter too for human beings and animals on the earth. Trees are natural home to many tribes living inside forests and home to all the birds. They give us timber to make furniture, refresh air, prevent soil erosion and floods, give cool and clean air in summer, source of products like gum, paper, rubber, medicine, rain, etc. We should understand the roles and importance of trees in our life and take a pledge to not destroy them as well as encourage people to plant more trees.
How to Save a Tree
Here are some effective ways to save tree and save life and environment on the earth:
- We should find out the reasons of trees removal in the particular region and analyze that whether tree was need to be removed because of being dead, damaged, diseased or planted in an inappropriate location.
- We should get proper information about the street tree removal by contacting city department, calling to local division of urban forestry, or writing a letter to the city forester regarding trees removal objection.
- We can contact our city council representatives regarding tree removal issue.
- We should join our hands together with neighbors and set a public hearing in front of officials regarding saving of the tree.
- We should research and collect all the benefits of trees in order to make case strong and effective.
- We should contact with the media and make them on our side to reach tree removal issue to the public and generate awareness.
- If trees have been removed, we should contact local governmental or nonprofit organization for ensuring re-plantation in the same area
Life is possible on the earth because of water, oxygen and trees and we cannot ignore that trees are source of oxygen and water on the earth. If we are destroying trees or forests, we are destroying our lives and environment from the green earth. Human beings are considered as the most intelligent creature on the earth, so we should understand our responsibility towards the nature and start saving trees, the green gold of earth.
Save Trees Essay 6 (400 words)
Trees are most valuable and important source of life on the earth. They are very critical to the healthy and vibrant communities on the earth. They benefit all the living things on the earth in some direct and indirect ways. Everything on the earth connect to each other and running according to the nature’s balance, if any disturbance occur to it whole environment may disturb and harm the lives on earth. Plants protect us from many natural disasters and nourish our lives in many ways. They keep our environment clean and earth green so, we are also responsible to them and try our best to protect trees. Large and mature trees are more benefiting in nature than smaller ones as they capture more carbon, filter green house gases at high rate, capture more storm water, provide big shadow and combat urban heat, reduce energy use and many more, so we should not cut them even in emergency.
Benefits of Trees
Here I have mentioned some real benefits of the trees which help you to understand that why trees should not be cut however need to be planted time to time.
- Mature trees help us to combat the climate changes by refreshing air and absorbing green house gases as they are the main source of climate change.
- Trees helps in air cleaning by refreshing the air as they absorb all the odors and pollutant gases in the environment.
- An acre of mature trees may provide required oxygen to 18 people per year.
- Trees help in combating summer heat as well as low winter temperature.
- Trees are best energy conservation and global warming management technique as they reduce the need of summer air conditioning by up to 50 percent.
- They save water by slowing down the water evaporation from ground through their shadow.
- Trees are natural water filter and play great role in preventing water pollution by allowing water to flow down to the earth below tree thus prevent rainwater to carry pollutants to the ocean.
- Trees prevent soil erosion by holding large amount of soil to one place.
- Trees provide us a strong shield to get protected from the ultra-violet rays and thus from the skin cancer and other skin disorders.
- Trees are good source of foods (like fruits, vegetables, etc), shelter, medicines, economy, etc.
- Trees have good healing property among patients having any health related complications like children with ADHD if they have direct exposure to the trees and nature.
- Trees are good source of identifying seasons, they reduces violence, and create economic opportunities to people.
- Trees are best teacher who never talk but shows everything. They are also best playmate of the kids.
- They are good example of unity in diversity.
- Trees are good source of reducing noise pollution, water pollution, air pollution and soil pollution.
By seeing all the benefits of trees mentioned above, we can completely understand the value of trees in our lives. Thus we should not cut trees, we always oppose the cutting of trees and forests, we should promote more tree plantation in the human crowded area, and motivate common people to save trees.
Save Trees Essay 7 (800 words)
Trees play great role in cleaning the air, soil and water and thus making earth a better place to live. People who live close to the trees are generally healthier and happier. Trees help us a lot through their limitless servings all across the life. As a human being, have we ever thought our responsibilities towards trees or only we are enjoying their benefits. Saving plants we are not showing any kindness to the plants instead we are showing kindness to our lives because life is not possible without trees on the earth. So, if we want to live life in healthy way, we have to save plants forever.
Importance of Trees
I have mentioned below some importance and precious value of trees which will help us to know why trees are called as green gold on the earth and most important for the healthy life.
- Trees add lots of value to our lives as well as and improve our living status by providing fresh oxygen and nutritious foods.
- Trees also fulfill our additional necessities like shelter, medicine, and other needs of our modern lifestyles.
- Trees in the society, community, streets, parks, playgrounds and backyards play great role in providing peaceful environment and aesthetically pleasing environment. Trees help to increase quality of life by providing cool shadow during our outdoor activities.
- Old trees in the living area become historic landmarks and source of town pride.
- Trees help in deflecting sunlight thus reduces heat island effect and keep environment clean and cool.
- Trees provide fresh oxygen and reduce air pollution by filtering harmful gases.
- They help in water conservation by preventing water evaporation.
- They prevent soil erosion and support wildlife.
- Trees are useful source controlling climate by managing the effects of sun, rain and wind.
- Trees are very essential in balancing the ecosystem in the nature.
- They are good source of absorbing and storing rainwater thus prevent from harms after storms.
- They are good source of food and shelter for forest animals. Birds make their nest on the trunk of plants.
- Trees have their personal and spiritual value as they look colourful and very beautiful. Some of the trees are traditionally worshipped by the people from ancient time.
- They are source of economy for many people as they are used commercially as a fuel, building construction, tools, furniture manufacture, sporting equipment, household items, paper and so many purposes.
Why to Save Trees
Below I have mentioned some points proving why we should save trees:
- Trees always clean and refresh air by releasing oxygen and filtering particulate matter including dust, micro metal particles, pollutants, green house gases (ozone, ammonia, nitrogen oxides, and sulfur dioxides), etc.
- Trees reduce smog and air pollution from the environment.
- They improve water quality, prevent water pollution, their root system reduce storm water runoff, prevent flooding and soil erosion.
- Trees are good source of energy saving because they reduce the use of air cooling system during summer season like electric fan, air conditioning, etc.
- Well-landscaped yards and real estate have nice value because of having positive economic influence on real estate they speeds up the sale of home.
- According to the Human-Environment Research Lab, trees are very effective in reducing violence level in the neighborhood.
- Four trees near by the home may save around 30% of the summer cooling costs whereas 1 million trees may save around $10 million energy costs per year.
- Forty to fifty trees help in removing approximately 80 pounds of the air pollutants per year.
- Trees have very less water requirement per year (400 trees need approximately 40,000 gallons of rainwater).
- A tree throughout its life period of 50 years provides oxygen worth $31,250.
- Trees around home boost its market value by 6 or 7% and add around 10% to a property’s value (according to the USDA Forest Service).
- A healthy and mature tree may provide cooling effect equivalent to air conditioner cooling ten room size area (20 hours/day, according to the U.S. Department of Agriculture).
As we have seen above about the importance of trees, values of trees in our lives and also well aware of why we should save trees; we should start a campaign of tree saving awareness in our surrounding to aware common public. We should promote people to highly participate in such type of events to know the issues related to reducing number of plants on the earth. We should be always active and open our eyes regarding existence of green gold on the earth. We should not involve in cutting trees and always oppose cutting of trees and forests. We should always participate in the tree plantation activities especially in the human crowded and polluted area.
