Question

Why doesn't a plant cell burst when placed in hypotonic condition?

• A. Cell wall is to withstand the osmotic turgor pressure of the cell
• B. The cell drains out of excess water
• C. The cell wall does not allow water into the cell
• D. The cell changes the salt concentration of the cytoplasm

Answer 1

The correct option is A

Cell wall is to withstand the osmotic turgor pressure of the cell

The cell wall provides mechanical support to the plant cell. When a plant cell is kept in a hypotonic solution, water enters the cell but it does not burst because of the pressure applied by the cell wall. Since it is rigid, it does not allow the cell to expand to an extent that it would burst.
