The accompany diagram shows plasmolysis in cell. A is normal turgid cell, B shows incipient plasmolysis and C is plasmolysed cell. Identify W, X, Y and Z respectively.

Options

A. Shrunken protoplast, Protoplast, Vacuole, Hypotonic solution
B. Shrunken protoplast, flaccid protoplast, Vacuole, External solution
C. Turgid protoplast, Protoplast, Vacuole, External solution
D. Shrunken protoplast, Protoplast, Vacuole, External solution

Answer

D

Explanation

The stage of plasmolysis when the protoplast just begins to contract away from the cell wall is called incipient plasmolysis.
The stage when the cell wall has reached its limit of contraction and protoplast has detached from cell wall attaining spherical shaped is called evident plasmolysis.
