Photosynthesis isthe making of food by plants. It is one example of how people and plants are dependent on each other in sustaining life. Photosynthesis provides us with most of the oxygen we need in order to breathe. We, in turn, exhale the carbondioxide needed by plants Photosynthesis is a process in which green plants use energy from the sun to transform water. carbon dioxide and minerals into oxygen and organic compounds The essential ingredients in making this food are sunlight, the chlorophyll that is present in green plants, water and carbon dioxide in the air. Photosynthesis happens when water is absorbed by the roots of green plants and is carried to the leaves by the xylem ( tubes that carry water) Carbon dioxide is obtained from air that enters the leaves through the stomata and diffuses to the cells containing chlorophyll. The green pigment substances needed for chlorophyll is uniquely capable of converting the active energy of light into a latent form that can be stored (in food) and used when needed. Sunlight is used to break down the water in the plant into oxygen which the plant gives off and we use to breathe. The hydrogen is then used with the carbon dioxide to creat food for the plants and ultimately food for animals as well.5. What is used to break down water in the plant into oxygen?
