WebRoots, stems, and leaves respire at rates much lower than are characteristic of animals. Only during photosynthesis are large volumes of gases exchanged, and each leaf is well adapted to take care of its own needs. The distance that gases must diffuse in even a large plant is not great. Each living cell in the plant is located close to the surface.

Web11 sep. 2024 · Plant leaves are adapted for photosynthesis and gas exchange. Roots absorb water and mineral ions through root hair cells and are transported up the plant by … WebGas exchange is achieved by diffusion. This is a process by which particles move naturally from a region where they are in high concentration to a region where they are in lower concentration. They move down a concentration gradient: the steeper the gradient, the faster the rate of diffusion.

WebSpecialised exchange surfaces: 1. ↑ Surface area = more substances can be exchanged (e. villi, alveoli, root hair cells) 2. Thin layers = less diffusion distance (e. alveoli) 3. Rich blood supply = good blood flow ensures a constant steep diffusion gradient 4. Ventilation to ...
