Transcript of The process by which a cell captures the energy in sunlight

A complicated Process
Photosynthesis is a very complicated process. During photosynthesis plants and some other organisms use energy from the sun to convert carbon dioxide and water into oxygen, and sugars including glucose. You can think of photosynthesis as taking place in two stages. Capturing the sun's energy and producing sugars.
In the first stage of photosynthesis it involves capturing the energy from sunlight. In plants this energy capturing process occurs in the leaves and other green parts of the plant, The chloroplasts in plant cells give plants their green color.The green color comes from pigments colored chemical compounds that absorb light. The main pigment found in chloroplasts of plants is chlorophyll. Similarly, the pigments capture light energy and use it to power the second stage of photosynthesis.
The Second Stage
In the second stage of photosynthesis the cell uses the captured energy to produce sugars. Inside the chloroplast, the water and carbon dioxide undergo a complex series of chemical reactions. The reactions are powered by the energy captured in the first stage. One of the products reactions is oxygen. The other products are sugar including glucose.

The process by which a cell captures the energy in sunlight and uses it to make food is called Photosynthesis.

The First Stage
If we did not have photosynthesis, we would not be able to breathe since oxygen comes from plants and we need oxygen to breathe.
