7.2 Photosynthesis occurs in chloroplasts in plant. cells. ï§ Chloroplasts are concentrated in the cells of the. mesophyll, the green tissue in the interior of the. leaf. ï§ Stomata are tiny pores in the leaf that allow. carbon dioxide to enter and oxygen to exit. ï§ Veins in the leaf deliver water absorbed by roots.
Both reactions are accomplished in organelles; chloroplasts are the sites of photosynthesis, and cellular respiration happens mainly in the mitochondria. Only photosynthetic organisms can make glucose, but all organisms must be able to use that energy. This energy usually comes in the form of ATP, or adenosine triphosphate. Cellular respiration produces ATP. The glucose is burned to produce the ATP. Cellular respiration consists of four steps.
