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.
Best Answer: photosynthesis occurs in the granum of a chloroplast where light is absorbed by chlorophyll; a type of photosynthetic pigment that converts the light to chemical energy. This reacts with water (H2O) and splits the oxygen and hydrogen molecules apart. Thus Oxygen is produced during the day time by plants.
