Facts About Green Plants

Plants form the backbone of the earth’s ecosystem. They provide a large amount of oxygen to the entire living world and absorb the harmful carbon dioxide gas, thereby, maintaining the earth’s temperature. The plants prepare food by the photosynthesis process and release oxygen that is inhaled by all life forms.
