Observe the plasma membrane of rheo leaf cells
Answers
Explanation:
Take a rhoeo leaf from the Petri dish. Fold the leaf and tear it along the lower side of the leaf. Using a forceps, pull out two small segments of thin transparent layer from the lower epidermis of the rhoeo leaf. Place the epidermal peels on both glass slides.
Answer:
Plasmolysis is the process during, which cells lose water when placed in a hypertonic solution, that is greater in the concentration of solutes compared with the inside of a cell. During plasmolysis, the organelles inside the cell shrink away from the cell wall, which results in severe water loss and leads to the collapse of the cell wall and finally results in cell death.
Osmosis is primarily responsible for the occurrence of plasmolysis. There are three stages in plasmolysis. Based on certain criteria, plasmolysis can be classified into two different types:
Concave plasmolysis – It is a reversible process.
Convex plasmolysis- It is an irreversible process.
