You must have heard stories of walking trees that move from place to place. However, in our day-to-day life, we never see plants moving from the place they are firmly rooted to.
The most obvious characteristic feature of plants is the one that distinguishes them from animals: their inability to move from a place to another.
However, plants are superior to animals when it comes to looking after themselves.They have the distinct ability to prepare their own food. Animals depend on plants or other animals for their food, directly or indirectly.
The process of plants preparing their food with the help of sunlight is known as photosynthesis. Plants use the green pigment on their body, called Chlorophyll, in order to make their food. In the process of photosynthesis, plants release oxygen, a gas vital for the existence of animals. Plants, therefore, are essential for animal life.
Plants, generally, have root, stem and leaves.They are usually divided into two broad categories: flowering plants. Mosses, ferns and horse- tails are some of the non-flowering plants.
However, there is so much diversity among flowering plants, and they outnumber non-flowering plants. About quarter of a million flowering plants can be found across the globe.The non-flowering plants include pines, redwood, ferns and mosses.
Algae, fungi and lichens were once considered as plants. However, they are no longer considered as true plants. They merely have some plant-like characteristics.There are about 400,000 kinds of plants on Earth today. The plant kingdom is one of the five kingdoms of living things.
