Flexi Says: The importance of plants to humans and just about all other life on Earth is staggering. Life as we know it would not be possible without plants. Plants supply food to nearly all terrestrial organisms. Plants maintain the atmosphere. They produce oxygen and absorb carbon dioxide during photosynthesis. Oxygen is essential for cellular respiration for all aerobic organisms. It also maintains the ozone layer that helps protect Earth’s life from damaging UV radiation. Plants recycle matter in biogeochemical cycles. Plants create habitats for many organisms.
