These are the foods plants use to live and grow. Plants use carbon dioxide in the process of photosynthesis.
Plants obtain energy from glucose made during photosynthesis. This carbon dioxide is stored as a four-carbon acid, and is eventually used during the process of photosynthesis on the next day. How can sunlight be a type of food? It was only because of photosynthesis that more and more oxygen was made which meant that animals and humans could develop.
An illustration of the photosynthesis process The leaves of a plant act as the primary site where the entire process occurs. Light dependent Reactions Light dependent reactions occur in the thylakoid membrane of the chloroplasts and take place only when light is available.
Here is the process in greater detail: Photosynthesis occurs in two stages commonly known as Light dependent Reactions and the Calvin Cycle.
Sometimes plant cells only have a few chloroplasts while others take up the whole space inside a cell. This oxygen is what we breathe and we cannot live without it. The second phase is called the Calvin Cycle because it was discovered and described by scientist Melvin Calvin.
It gives the plants energy to grow. In the leaves of a plant is a substance called chlorophyll. So chlorophyll actually reflects green light and absorbs blue and red light.
