Photosynthesis Process of turning light energy into chemical energy

Chloroplasts produces food for the cell. The organelles are only found in plant cells and some protists such as algae. Animal cells don't have chloroplasts. Chloroplasts change light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast.

Chlorophyll is the pigment or the green color of plants, leaves, and algae. It absorbs blue and red light rays which turns it green. And it also reflects green light rays which gives plants there unmistakable color.

During photosynthesis the plants capture the suns light energy. Plants use that energy to turn water and carbon dioxide into a sugar called glucose. The glucose makes energy and makes other substances like cellulose and starch.

An electron transport chain is a series of compounds that transfer electrons from electron donors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane

The Calvin cycle is the light independent reactions in photosynthesis that take place in three key steps. Although the Calvin Cycle is not directly dependent on light, it is indirectly dependent on light since the necessary energy carriers (ATP and NADPH) are products of light-dependent reactions.
