Chapter 10 – Photosynthesis Overview The chloroplasts of plants capture light energy from the sun and convert it to chemical energy stored in sugar and other organic molecules. This conversion process is called photosynthesis . We will consider the two stages of photosynthesis: the light reactions, in which solar energy is captured and transformed into chemical energy; and the Calvin cycle, in which the chemical energy is used to make organic molecules of food. 10.1 Photosynthesis converts light energy to the chemical energy of food Chloroplasts: The Sites of Photosynthesis in Plants The color of the leaf is from chlorophyll , the green pigment located within chloroplasts. It is the light energy absorbed by chlorophyll that drives the synthesis of organic molecules in the chloroplast. Chloroplasts are found mainly in the cells of the mesophyll , the tissue in the interior of the leaf. CO2 enters the leaf, and oxygen exits, by way of pores called stomata
