Biology

The correct answer is: A.A and R are correct and R is the correct explanation of A.

Here's the reasoning:

1.Assertion (A): "Cell walls prevent the cell from bursting during exosmosis."

This is true. Exosmosis refers to the movement of water out of the cell, often in a hypertonic environment. When a plant cell loses water, the cell membrane could shrink away from the cell wall (plasmolysis), but the cell wall prevents the cell from collapsing or bursting under the loss of water, maintaining the structural integrity of the cell. Without a cell wall, the cell would be much more vulnerable to changes in water balance.

2.Reason (R): "Cell walls are strong and give support...
