Most people would argue that if it is a living thing and not a microbe, a human being or an animal, then it is a plant. There are many types of plants, and they take different forms. It could be a tree, a blade of grass, algae floating on water or flowers in a pot.
There are thousands of known plant species, and scientists have classified them according to their kingdoms, divisions, classes, orders, families, genus and species for easy identification.
There is, however, one thing that they have in common, despite their diversities in size and form. They all require photosynthesis, a process by which all plants convert energy obtained from the sun into chemical energy needed for growth and survival.
Many plants such as flowers, shrubs or trees have roots that are used both for support and for pulling nutrients from the ground. The roots also store up minerals and nutrients for later use. Plants hold together all of life on earth and act as a critical supply for human well-being. Different types of plants have various uses too. Most plants such as vegetables are edible as a whole or parts of them.
Huge trees or shrubs are used for fencing around a home while others are used as flowers due to their attractive colors. Herbivorous animals depend on plants as their source of food. Other purposes include medicine, cleaning the air, stabilizing the land, making instruments, and cosmetics among many others. It is, therefore, important to protect the plants we have around us for the ultimate survival of the earth.
