Read the given statements, which refer to different stages of plasmolysis. Select the correct option regarding them. (i) First stage of plasmolysis, when the osmotic concentration of cell sap is just equivalent to that of the external solution (ii) Protoplast withdraws itself from the corners of the cell wall (iii) Protoplast gets detached from the cell wall and attains a spherical shape

Answer: (A)

Solution

Incipient plasmolysis is the earliest stage, when the cell's osmotic concentration just equals that of the external solution and turgor pressure first falls to zero (i). Limiting plasmolysis follows, as the protoplast
