Witryna14 sty 2024 · Gaseous exchange occurs in the root hair of young terrestrial plants. Oxygen in the air spaces in the soil dissolves in the film of moisture surrounding soil particles and diffuses into the root hair along a concentration gradient. It diffuses from root hair cells into the cortex where it is used for respiration. WitrynaGas exchange in animals For an organism to function, substances must move into and out of cells. Three processes contribute to this movement – diffusion, osmosis and …
