WebDiffusion also occurs in plant cells. In all green plants, water present in the soil diffuses into plants through their root hair cells. The movement of ions across the neurons that generates electrical charge is due to diffusion. … WebThe concentration of mineral ions is lower in the soil relative to the inside of root hair cells. Due to this concentration gradient, active transport is needed to pump the minerals into the root hair cell. Carrier proteins that are selective for specific mineral ions mediate active transport; this is a form of uniport.
