How do plants control turgor pressure?

Question

beccaboo333 · Answer

When a plant cell stores ions, sugars and other solutes in its vacuole, this causes an influx of water. The influx of water results in a large turgor pressure exerted on the plant cell wall. This makes plant cells to become turgid, thus, helping the plants to stand upright, and do not wilt.

It requires water to do so. And for the uptake of water from its surroundings, a cell must keep its internal fluid or the cell sap at a higher solute concentration or lower water potential. This results in "endosmosis". Once water enters the cell, the protoplast swells and the cell membrane exerts a pushing force on the cell wall which is called the turgor pressure.
So basically, it has to regulate the flow of solute particles or ions across its cell membrane and keep its cell sap at a higher solute concentration or lower water potential, compared to its surrounding medium.
