Question

Choose the correct answers from the alternatives given.
When a plant cell is placed in pure water, it will

• A. Become rigid because of turgor pressure
• B. Lose water and wilt
• C. Swell and burst
• D. Alter its cell wall composition so that it becomes impermeable to water

Answer 1

The correct option is A Become rigid because of turgor pressure

Pure water is a hypotonic solution that causes endosmosis. The water diffuses into the cell causing the cytoplasm to build up pressure against the wall. This pressure is called turgor pressure that causes rigidity of the cell and the cell does not burst. This turgor pressure is responsible for the enlargement and extension of the cells during growth.

Hence, the correct answer is 'Become rigid because of turgor pressure'.
