A) osmosis
B) aquaporins
C) turgor pressure
D) simple diffusion
E) equilibrium

Question

Quizplus · Accepted Answer

Turgor pressure is the pressure exerted on the cell wall of a plant cell due to the influx of water, which helps keep the cell rigid and the plant upright. This pressure is a result of osmosis, which is the movement of water across a selectively permeable membrane from an area of high water concentration to an area of low water concentration. The plant cell wall, with its cellulose fibers, limits the amount of water that can enter the cell, and aquaporins are proteins that facilitate the movement of water across membranes. Simple diffusion refers to the movement of particles from an area of high concentration to an area of low concentration, without the need for a membrane or energy input. Equilibrium refers to a state of balance or equal distribution of particles.
