Detailed explanation-1: -We should take care of plants because plants help us in many ways, like: (i) Plants provide us food and clean the air. (ii) Plants give us wood, medicines, cotton and many other things. (iii) Plants maintain carbon-di-oxide-oxygen balance in air.
Detailed explanation-2: -We should take care of plants and animals because these jointly sustain life on the Earth. Plants provide the food and oxygen for the survival of animals and animals in return provide carbon dioxide to plants for photosynthesis. Survival of plants and animals is very important for the survival of humans on the Earth.
Detailed explanation-3: -Plants are important for the survival of living organisms as they absorb CO2 and release O. They are also the main producers of food because of the presence of chlorophyll pigment. They provide us with day-to-day life things such as wood, timber, paper, etc.
Detailed explanation-4: -Plants produce their own food by the process of photosynthesis and they supply food to nearly all terrestrial organisms, including humans. Plants maintain the atmosphere. They produce oxygen and absorb carbon dioxide during photosynthesis. Oxygen is essential for cellular respiration for all aerobic organisms.
