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.
1. Photosynthesis is an energy-storing process that combines carbon dioxide and water in the presence of light with the aid of chlorophyll; oxygen is a by-product. All life depends on photosynthesis, which takes place in chloroplasts. 2. Carbon dioxide constitutes 0.035% of the atmosphere, but the percentage has been rising in recent years.
