Turgor pressure in a plant cell results from pressure on the plasma membrane and cell wall placed in

A. a hypertonic solution
B. either a hypotonic or hypertonic solution
C. an isotonic solution
D. a hypotonic solution



Answer :

Final answer:

Turgor pressure in plant cells is generated by water entering the cell, creating pressure on the cell wall and plasma membrane. This pressure supports the plant's structure and prevents bursting. Plant cells in hypotonic solutions gain turgor pressure, while cells in hypertonic solutions lose turgor pressure and wilt.


Explanation:

Turgor pressure in plant cells is the result of water entering the cell due to osmosis, creating pressure on the cell wall and plasma membrane. This pressure pushes the plasma membrane against the cell wall, providing structural support to the plant.

When plant cells are placed in a hypotonic solution, water enters the cell, increasing the osmotic pressure inside the cell. This leads to the generation of turgor pressure, which stiffens the cell wall and prevents the cell from bursting.

In contrast, if plant cells are placed in a hypertonic solution, water leaves the cell, causing the cell to lose turgor pressure and resulting in wilting.
