Question

Tradescantia leaf epidermal peel was taken and

1. Placed in salt solution for five minutes.
2. After that it was placed in distilled water.

When seen under the microscope what would be observed in a and b?

Answer 1

1. The cells would have shrunk when seen under the microscope because the salt solution is hypertonic causing water to move out of the cell thus leading to exosmosis.
2. After that when it was placed in distilled water, the cell regains its turgidity as it absorbs water and deplasmolysis occurs.
