plants are very important in our life we can say plants are just like the backbone of our life. If we think about our everyday life you will notice that everything we eat come from plants, rather directly or indirectly they synthesise their own food and stores the energy as starch like photosynthesis. Plants help to maintain the oxygen and water level through photosynthesis .and transpiration respectively. Also helps to maintain the carbon dioxide level in the air.
