Question

The vacuole in mature plant cells plays a crucial role in maintaining turgor pressure. How does it achieve this?
Options
A By synthesizing cellulose for the cell wall, making it rigid.
B By actively pumping water out of the cell, preventing bursting.
C By accumulating solutes and water, exerting pressure against the cell wall.
Correct Answer
D By producing hydrolytic enzymes that digest excess water.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Section 7.7 states that one function of the vacuole is 'Maintenance of turgor pressure — the pressure of the cell contents against the cell wall, essential for maintaining rigidity in non-woody tissues.' This pressure is generated by the osmotic uptake of water due to stored solutes.

Hint

Recall the principle of osmosis and how a large internal compartment filled with fluid would affect cell rigidity.
