A tree is a tall plant with a trunk and branches made of wood. Trees are the largest and oldest living things on Earth. There are several parts that make up a tree. The main parts of a tree include roots, trunk, branches and leaves. Trees reproduce through pollination via insects, wind and animals. Trees produce seeds that can grow into a separate adult tree if the conditions are right.

Facts about Trees

  1. According to the fossils, scientists believe that trees have been on Earth for 370 million years.
  2. Trees can live for thousands of years.
  3. The oldest tree ever discovered is approximately 5,000 years old.
  4. There are more than 60,000 species of trees on Earth.
  5. Brazil has the most species of trees. There are 5,776 tree species there.
  6. Trees usually grow to over 90 metres. Some trees can grow to around 100 meters in height.
  7. Plants that are not tall enough to be considered trees are often called shrubs.
  8. A single tree has many roots. The roots usually grow underground. They help the tree to stay upright and alive. They carry water and nutrients from the soil to the tree.
  9. The trunk is the main body of the tree. It is protected by an outside layer of bark.
  10. Branches grow from the trunk. They spread out so that the leaves can get more sunlight.
  11. Trees have growth rings inside their trunk. You can count the tree rings to find out how old it is.
  12. Trees are able to make their own food through the process of photosynthesis. Through photosynthesis, trees take carbon dioxide, water and sunlight and turn them into oxygen and sugars.
  13. Tree leaves are the parts that take in the sunlight that is needed for photosynthesis. The more sunlight they get, the healthier the tree will be.
  14. The leaves of a tree are green most of the time, but they can come in many colors, shapes and sizes. Trees with leaves all year round are called evergreens, and those that shed their leaves are called deciduous. Deciduous trees and shrubs generally lose their leaves in Autumn, and they grow back in Spring.
  15. Trees are able to communicate and defend themselves against attacking insects. They can flood their leaves with chemicals called phenolics when the insects begin their raid. They can also signal danger to other trees so they can start their own defense.
  16. Different parts of a tree grow at different times throughout the year. Typically, most of the foliage growth happens in spring, followed by trunk growth in summer and root growth in fall and winter.

Benefits of Trees

  • Trees provide natural materials such as wood and paper. They are very useful to us and are used for lots of things. The wood from trees is used for building houses, boats, and furniture. The wood can also be used as fuel for a fire, both for warmth and cooking. The paper you use at school is also from trees.
  • Trees provide food. They are sources of food like fruit and nuts. The sap from some trees is used to create syrups.
  • Tree rings can predict climate change. A tree’s rings do not only reveal its age, they can also indicate the occurrence of natural disasters such as volcanoes or a drought event. In the years of good growth and supply of resources, the ring is thick. When resources are scarce in the ecosystem, it becomes thin.
  • Trees help reduce the effects of climate change. They produce oxygen and reduce the amount of carbon dioxide in the atmosphere. A mature tree can absorb more than 48 pounds of carbon dioxide each year.
  • Planting trees can help reduce your energy costs. A shade of a tree can help cool your home in the summertime. Not only do they provide shade in the summer, but serve as a windbreak in the winter, too.
  • Trees can help reduce stress. Research suggests that being around trees is good for our mental and social well-being. Research also suggests that nature experiences help us feel kinder toward others. This is partly because trees release chemicals called phytoncides. When we breathe them in, it can reduce blood pressure, lower anxiety levels, and increase pain threshold.
  • Trees block noise by reducing sound waves. They reduce noise through a phenomenon called sound attenuation, which is the reduction of sound intensity. Leaves, twigs, and branches on trees absorb and deflect sound waves to mask unwanted noise.
  • Trees improve water quality. As rain falls to the Earth, it is slowed and filtered by trees, helping it soak into the soil. Trees then serve as natural sponges, collecting and filtering rainwater and releasing it slowly into streams and rivers. They also prevent soil from eroding into our waterways, reduce stormwater runoff, and lessen flood damage.

Species of Trees

Trees include a huge variety of species. In this lesson, we are going to know 4 of them, which are:

  1. Palm Trees
  2. Banyan Trees
  3. Dogwood Trees
  4. Cherry Blossom Trees

Palm Trees

Palm trees are one of the most common planted trees all over the world. Throughout history, palms have had important roles in humans’ lives. Many common products and foods come from palms. There are about 2600 species of palm trees all around the world, from the desert to the rainforest. Most palms live in tropical, subtropical, and warm temperate climates.

Most palms are a straight, unbranched stem. They have two different types of evergreen leaves: palmate and pinnate. Palmate leaves grow in a bunch at the end of a stem. Pinnate leaves are like feathers, growing all along one side of a stem. The fruit of the palm is usually a single seed surrounded by flesh. Some kinds may contain two or more seeds in each fruit. Well known palm trees are Coconut palm, Date palm and Oil palm.

Banyan Trees

Banyan is a fig tree that begins its life as an epiphyte. An epiphyte is a plant that grows on another plant. The branches of the banyan produce aerial roots. These roots descend and take root in the soil to become new trunk. Banyan is an evergreen tree that grows in tropical climate and in almost any soil.
