Photosynthesis
Photosynthesis is the process by which green plants use sunlight energy to make their own food. It takes place inside the chloroplasts of plant cells.
What is photosynthesis?
Green plants make their own sugars by the process of photosynthesis.
Photosynthesis takes place inside the chloroplasts of plant cells. Chlorophyll, the green pigment found in chloroplasts, traps light energy, usually from the sun.
Plants also take in raw materials from the environment, water through their roots and carbon dioxide through the stomata of their leaves by diffusion.
Sugar is made for plants to use and oxygen is released into the atmosphere which is very useful for humans and other organisms that carry out aerobic respiration.
Overall energy conversion during photosynthesis
Energy cannot be produced or used up, it can only be converted from one form to another.
In photosynthesis, light energy is converted into chemical energy which is stored in the sugar molecules produced. This stored energy is then available to the plant cells to use.
