A tree is a tall plant with a trunk and branches made of wood. It can live for many years. The four main parts of a tree are the roots, trunk, branches, and leaves.
See the fact file below for more information on Trees or alternatively, you can download our 27-page Trees worksheet pack to utilize within the classroom or home environment.
Key Facts & Information
STRUCTURE AND GROWTH
- A tree is a type of perennial plant with an elongated stem or trunk that usually supports branches and leaves.
- In some contexts, the definition of a tree may be narrower, encompassing only woody plants with secondary growth, plants suitable for lumber production, or plants taller than a certain height.
- Tree growth and branch lengthening start with the bud. The apical meristem, whose cells divide and elongate at the bud’s foundation to create upward growth with a dominant crown tip, is in charge of tree height growth.
- If the top of a tree is damaged, multiple crowns may form. Because some conifers cannot produce these growth cells, height growth stops at the crown tip.
- The underlying patterns of wide or narrow rings record the fluctuations in tree growth from year to year. As a result, in addition to the tree’s age, the patterns frequently include the weather history at the location where it grew.
- Tree rings in temperate climates can show their age through their annual rings, and they can also help estimate the age of wood used to build buildings or wooden objects.
- Cross-dating is the process of matching ring patterns in wood samples with known and unknown ages.
- Furthermore, a tree structure is made up of three parts: the trunk, the crown, and the roots. The trunk’s functions include supporting the crown and supplying water and nutrients from the roots to the leaves via branches and from the leaves back to the roots.
- On the other hand, the roots serve to anchor them in the soil, as well as to absorb moisture and mineral substances and transport them to the trunk.
- In addition, they are divided into three major organs: roots, stems, and leaves. Most higher vascular plants’ leaves are the primary photosynthetic organs.
- They are linked to the rest of the plant by a continuous vascular system, allowing for the free exchange of nutrients, water, and photosynthesis end products, particularly oxygen and carbohydrates.
CLASSIFICATION OF TREES
- All tree species are classified into two main groups, namely deciduous and evergreen.
- Deciduous trees – In horticulture and botany, deciduous means “falling off at maturity” or “tendency to fall off”. At the end of the growing season, deciduous ones shed their leaves.
- The leaves of a tropical and subtropical deciduous tree fall as a mechanism to conserve water during the dry season.
- Trees at these latitudes do not experience the same reduction in daylight hours as temperate deciduous ones.
- Deciduous trees such as oak, walnut, elm, and maple shed their leaves in the fall in North America, Europe, and temperate countries.
- This is typically followed by the leaves changing to beautiful colors such as orange, brown, and yellow. In tropical countries, deciduous trees shed their leaves during the dry season.
- Evergreen trees – Unlike deciduous trees, evergreen trees do not shed leaves in the winter season. Instead, they stay green for more than one growing season.
- Evergreen trees are classified into 14 family groups. They help in providing color and landscapes all year round in gardens or forests.
- They are also responsible for the breathtaking appearance of forests during the winter seasons; some are also often used as Christmas trees.
- These include cedars, pines, firs, juniper, holly, thuja, cryptomeria, olives, hemlocks, eucalyptus, bamboo, and spruce trees.
- Evergreens with scales or needle-like leaves are also common.
IMPORTANCE OF TREES
- Trees are beneficial to all humans, not just the environment. Excess carbon dioxide (CO2) in our atmosphere as a result of human activities and pollution contributes to climate change.
- They contribute by absorbing CO2 and storing it while releasing oxygen, which humans need to survive, back into the atmosphere.
- Tree shade reduces water evaporation from dehydrated lawns.
- The majority of newly planted ones require only fifteen gallons of water per week. As trees transpire, they add moisture to the atmosphere.
- They also prevent water pollution as they reduce runoff by breaking down rainfall and allowing it to flow down the trunk and into the earth beneath the tree.
- This keeps pollutants from entering the ocean through stormwater. When trees are mulched, they act like a sponge, filtering the water naturally and recharging groundwater supplies.
- They preserve a location’s distinct character and foster community pride. Woodlands can be used to educate people and bring people together for activities such as walking and bird watching.
- They are also great places for kids to play and explore their sense of adventure. This teaches them to give importance to nature so that as they grow, they learn to respect nature, especially the trees and those that dwell in them.
- Furthermore, they provide shelter not only for humans but also for many animals.
- From the lowest levels to the highest canopies, they offer food and habitats to a wide variety of wildlife.
- Many farmers use them to construct hives to attract bees to their land for pollination and honey production.
- Trees are not only necessary for life, but as the longest living species on the planet, they also provide a link between the past, present, and future.
- It is critical that woodlands, rainforests, and trees in urban settings, such as parks, are preserved and managed sustainably around the world.
TREE CONSERVATION EFFORTS
- There are several ways to conserve trees, one of which is to use less paper.
- While paper production necessitates continuous tree planting, the amount of energy and resources required to produce paper is not environmentally friendly.
- Find ways to minimize the use of paper whenever possible. Look for alternatives to commonly used paper products, such as cardboard, printer paper, and paper cups.
- When buying paper, it’s important to inspect and read the packaging to see if it’s made of recycled materials; buying from environmentally conscious companies can also help.
- It’s great if you recycle on your own, but if you don’t support the manufacturers who use your recycled paper, they’ll find it much more difficult to justify the extra cost.
- Reducing meat consumption also aids the conservation of trees, as it often prevents the destruction of vast swathes of forests and woodlands to make room for all the animals.
- The use of social media platforms to spread tree conservation information could be beneficial.

Frequently Asked Questions
What are the two main types of trees?
The two main types of trees are deciduous and evergreen. Their main difference is deciduous trees shed their leaves based on seasons, while evergreen trees keep their leaves all year round.
What is the importance of trees?
Trees play a major role in all living things on the planet. Apart from providing shelter and picturesque surroundings, trees and other plants are responsible for half of our Earth’s oxygen supply. They also play a crucial role in the water cycle and help prevent air and water pollution. They provide homes to many kinds of animals.
How can we help conserve trees?
There are many things you can do to help conserve trees. You can choose to use recycled paper. Using less paper, in general, is also a great way to help lessen the need to produce more paper products. Lastly, it would be a great idea to learn about conservation efforts in our area so we can participate in them.
