"WebIn Figure 2, water will move from a region of higher to lower water potential until equilibrium is reached. Solutes (Ψ s), pressure (Ψ p), and gravity (Ψ g) influence total water potential for each side of the tube (Ψ total right or left), and therefore, the difference between Ψ total on each side (ΔΨ).

WebWe know that in higher green plants, some substances enter the living cells through the aerial organs—the diffusion of CO 2 and O 2 from the atmosphere into the plants is principally through stomata. From soil, water and ions of simple inorganic salts pass into the plants through the root cells by a process which is basically diffusion, though greatly … WebThe lungs are made up of tiny sacs called alveoli which presents a very large surface area for gaseous exchange. The lungs are well supplied with blood due to lots of capillaries covering the alveoli, constantly maintaining a large diffusion gradient, air is able to pass easily down this gradient due to the alveoli having very thin walls (one ...
