Question

Turgidity of the cells is maintained by

• A. Wall pressure
• B. Turgour pressure
• C. Diffusion pressure
• D. Osmotic pressure

Answer 1

The correct option is B Turgour pressure

The pressure exerted by water inside the cell against the cell wall. When a plant cell stores ions, sugars and other solutes in its vacuole, this causes an influx of water. The influx of water results in a large turgor pressure exerted on the plant cell wall. This makes plant cells to become turgid, thus, helping the plants to stand upright, and do not wilt. Thus, option B is the correct answer. Wall pressure, diffusion pressure, and osmotic pressure can not maintain the turgidity of the cells.

So, the correct answer is option B.
