​PLANTS

Plants are living beings. They need food, water and air for survival.

Plants derive their food from the earth and the air. If you look at their roots, you will find that the ends of these roots are like fine fibers. We call them root-hairs. They absorb water and minerals, then transport them upwards to the leaves through the trunk and the branches. It is the leaves which prepare the food.

​PLANTS

The green material, chlorophyll, prepares the food like a machine. It converts the carbon dioxide taken from the air and water from the ground into sugar with the help of sunlight. This chemical reaction is called photosynthesis. In fact, the chlorophyll takes energy from the sunlight and uses it to synthesize the hydrogen from water and carbon from carbon dioxide for making sugar. This reaction also gives out oxygen and water which are excreted by the leaves.
