What is Tree?

Trees are the plants, which looks bigger with lots of branches and leaves. There is no any proper scientific definition about the tree. But, authors define the trees by their own way. Generally, a plant is considered a tree if its height reaches more than 13 feet, has woody a stem, and lives for many years.

Types of Trees

There are the two main types of trees; one is evergreen and other is deciduous. Both of them are slightly different.

  • Roots: Roots are part of the trees which remain in the soil. They absorb the water and nutrients from the soil for the whole tree. Also, they provide the anchor to the tree.
  • Trunk: Trunk provides support to all parts of a tree and gives the tree its shape. It stores and transports the water, nutrients, and food to all parts of the plants.
  • Crown: Crown is the top of the tree, which contains all the leaves and branches. It has different shapes and sizes for different trees.
  • Branches: Branches distributes the leaves in the air evenly. They grow at different positions so that leaves can get the necessary air and the sunshine.
  • Leaves: They are like the food factories for a tree. They produce food for the tree in the photosynthesis process and gives the precious oxygen to animals and humans. Leaves contain a substance called chlorophyll, which gives them a green color and used in the photosynthesis.

Trees and Humans

Trees are giving us food, wood, and many other necessary materials. They provide us fresh oxygen and helps to reduce the pollution. But, we as a human are destroying the trees for land and wood. The number of trees across the world is decreasing sharply. A lot of forests have been destroyed for the land and agriculture. As a result, many animals have become endangered species and air pollution has raised.
