in a project work two rheo peels were taken , one peel was put in a petri dish containing cold water and peel was put in a petri dish containing hot water . After a while both were transferred to hypertonic soln . The peel s were observed under microscope . Aman was the only one who noticed difference in the observations of both the peels . Answer the followings questions based on above information 1) what will be the difference in observation of both the peels 2)what are the values displayed by aman. plzzzz answer fastly

When the first rhoeo leaf peel is kept in a petri dish containing cold water, the leaf cells will be alive and they absorb the water due to the process of endosmosis.
After a while, this peel is transferred into a hypertonic solution (a sugar syrup whose concentration is more when compared with cell). When observed under a microscope, it can be noted that plasmolysis occurs (i.e.) water from the living cell flows out of the membrane to the outer liquid.
When the second rhoeo leaf peel is kept in another petri dish containing hot water, the cells of the leaf die.
After a while, this dead peel is transferred into a hypertonic solution and it can be observed under the microscope that no plasmolysis had taken place.
Thus dead cells do not exhibit plasmolysis, but only the living cells do.
