Final answer:
Osmosis and diffusion are essential plant processes involving water uptake, nutrient transport, and gas exchange.
Explanation:
Osmosis and diffusion are crucial processes in plants. Osmosis aids in the movement of water molecules across a semi-permeable membrane to equalize the concentration of solutes, while diffusion facilitates the movement of gases, nutrients, and wastes across cell membranes.
Plasma membranes of plant cells contain aquaporins, specialized water channels that enhance water uptake in plants. Additionally, the transport of essential nutrients like zinc, iron, and nitrogen through membranes relies on diffusion mechanisms.
The exchange of gases like oxygen and carbon dioxide in plants occurs through processes of diffusion, with factors like intercellular air spaces and stomata playing vital roles.
