Guard cell function - help to regulate the rate of transpiration by opening and closing the stomata
Active transport
osmosis - the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane
Diffusion- the net movement of anything (for example, atoms, ions, molecules, energy) generally from a region of higher concentration to a region of lower concentration.
Example of active transport in root hair cell - Diffusion is the net movement of anything (for example, atoms, ions, molecules, energy) generally from a region of higher concentration to a region of lower concentration.
3limitingfactorsforphotosynthesis - For plants to take up mineral ions, ions are moved into root hairs, where they are in a higher concentration than in the dilute solutions in the soil
