Q. Read the given statements regarding the different stages of plasmolysis and choose the correct option I. First stage of plasmolysis, when osmotic concentration of cell sap is just equivalent to that of external solution II. Protoplast withdraws itself from corners of the cell wall III. Protoplast gets detached from the cell wall and attains a spherical shape I II III
A) Incipient Limiting Evident plasmolysis plasmolysis plasmolysis
B) Limiting Incipient Evident plasmolysis plasmolysis plasmolysis
C) Limiting Evident Incipient plasmolysis plasmolysis plasmolysis
D) Evident Incipient Limiting plasmolysis plasmolysis plasmolysis
Explanation
Limiting plasmolysis is the first stage of plasmolysis, during which the pressure on the wall is reduced and the wall contracts causing the reduction in cell wall simultaneously. During the second stage, the protoplast withdraws itself from the corners. This stage is known as incipient plasmolysis. Due to continued exosmosis, protoplasts shrink further and withdraws from the cell wall except on or few points. This is the last stage and is called evident plasmolysis
