Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
When a plant cell is placed in pure distilled water, the water enters into the cell. Cell wall is outer rigid, protective and supportive covering of a plant cell, which prevents the bursting of plant cell by inhibiting excessive endosmosis. On the other hand animal cells rupture if they are placed in distilled water, due to the absence of cell wall.
So, the correct answer is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'
