Which force opposes the entry of water into a turgid plant cell?
Show answer and explanation
Correct answer: Pressure of the cell wall on the protoplast
Wall pressure (also called pressure potential) is exerted by the rigid cell wall against the expanding protoplast. It opposes and ultimately balances turgor pressure in a fully turgid cell, preventing further water entry.
