G. regulates water levels in plant cells

WebThe force, that is generated when an influx of water causes the plasma membrane to push against the cell wall, is called turgor pressure. In contrast to animal cells, plant cells have rigid cell walls that limit the osmosis-induced expansion of the plasma membrane. By limiting expansion, the cell wall prevents the cell from bursting and causes ... WebOsmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from …
