Question

Two Rhoeo peels were taken. One peel was put in a petridish containing cold water and the other was put in a petridish containing hot water. After a while both were transferred to hypertonic solutions. If the peels were observed under the microscope.
a) Will there be any difference in the observation of both the peels. Yes or no.
b) Mention diagrammatically your observation in each case.
c) Explain the reason for your observation in each case.

Answer 1

Answer:

The cells of the leaf placed in cold water will remain living and absorb water due to endosmosis while the cells of leaf placed in hot water will become dead and dead cells do no absorb or loose water.

When both of these leaves are placed in hypertonic solution and observed under microscope, the leaf which was placed in cold water will show plasmolysis while the leaf placed in hot water will not show plasmolysis. Thus, it shows that only living cells undergo plasmolysis not the dead cells.
