"WebOsmotic pressure is a colligative property of solutions that is observed using a semipermeable membrane, a barrier with pores small enough to allow solvent molecules to pass through but not solute molecules or ions. The net flow of solvent through a semipermeable membrane is called osmosis (from the Greek osmós, meaning “push”). " - Highest osmotic pressure in plant

Root pressure Definition, Botany, Mechanism, & Facts

Osmotic pressure is the main agent of support in many plants. The osmotic entry of water raises the turgor pressure exerted against the cell wall, until it equals the osmotic pressure, creating a steady state. When a plant cell is placed in a solution that is hypertonic relative to the cytoplasm, water moves out of the cell and the cell shrinks. In doing so, the ce… WebOsmotic pressure will be highest in option B: Halophytes. Osmotic pressure is the pressure exerted by the movement of water through a semi-permeable membrane from …
