- Intake of Water and Carbon dioxide: Water and carbon dioxide are the raw materials of photosynthesis. Plants have mechanisms for
the intake and transport of these raw materials. Water, present in soil, is absorbed by roots and root hairs through osmosis. This water is eventually
transported to leaves through xylem vessels. The air that enters leaf through tiny pores (stomata) reaches into the air spaces present around
mesophyll cells. This air carries CO2, which gets absorbed in the thin layer of water surrounding
mesophyll cells. From here, the carbon dioxide diffuses into mesophyll cells.
