Which plant structure will open and close in response to turgor pressure, helping to regulate transpiration?

Question

Quizplus · Accepted Answer

A plant cell that is full of water will bulge. Turgor pressure is the force of the water creating this bulge. Stomata open and close due to turgor pressure changes within guard cells. When water enters the guard cells, turgor pressure is created and the guard cell's unique "banana" shape causes the cells to bow out and expose the pore stoma); when water leaves the guard cells, turgor pressure is lost and the pore is once again covered. For transpiration to occur, the stomata must stay open.
