Question

What are two different ways a plant could control turgor pressure?

Answer 1

The ways that a plant could control turgor pressure is by pumping ions and Opening and closing of stomates to control evaporation from leaves.  Of course, 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.

Answer 2

Turgor pressure (hydrostatic pressure) of the plant can be described as the force within the cell that pushes the plasma membrane against the cell wall. Turgor pressure within plant cells is regulated by osmosis (travel of the water from an area with a low concentration of solutes, to one with a higher-solute concentration). There are two mechanisms for the regulation of turgor pressure.
1. The semipermeable membrane, which only allows some solutes to travel in and out of the cell. Also, it can maintain a small amount of pressure.
2. Transpiration by opening and closing of stomates to control evaporation from leaves, which results in water loss and decreases turgidity in cells.
