Biology Presentation

Biology Presentation . Okan Atilan. Water Uptake in Plants. Root Hair Cells. They cover the part of the root that absorb water. They increases the surface area and hence, speeds up water uptake. When water is absorbed, it has to through the cortex and the endodermis, to reach the xylem.

Diffusion of Water (Osmosis)

Diffusion of Water (Osmosis). To survive, plants must balance water uptake and loss Osmosis determines the net uptake or water loss by a cell and is affected by solute concentration and pressure. Water potential is a measurement that combines the effects of solute concentration and pressure
