Turgor Pressure in Plant Cells Is

Question

Turgor pressure in plant cells is
A) a result of the walled cell being in a hypotonic environment.
B) due in part to osmosis.
C) necessary to keep plants from wilting.
D) the force of water against the inside of the cell wall.
E) All of the answer choices are correct.

Accepted Answer

All of the answer choices are correct. Turgor pressure is the pressure exerted by the contents of a cell against its cell wall, and it results from water moving into a plant cell due to osmosis. This pressure is necessary to keep plant cells rigid and maintain the overall stability of a plant, preventing it from wilting. Turgor pressure only occurs in plant cells because they have a rigid cell wall, which provides resistance to the pressure of the cell's contents. Turgor pressure is a result of the walled cell being in a hypotonic environment, where water moves into the cell due to the concentration gradient across the cell membrane.
