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
