Assertion :To counteract the increase in turgor pressure in plant cells, the cell wall produces an equal and opposite pressure, i.e., wall pressure. Reason: When plant cells undergo endosmosis, they swell but do not burst.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Plant cells are surrounded by a rigid cell wall. When water gains entry into the cell through the process of endosmosis, the protoplasm swells and increase in volume. The protoplasm exerts pressure on the wall. This pressure is called as turgor pressure. As per Newton's Law, the wall exerts an equal pressure in opposite direction. This pressure is called as wall pressure. As the two pressures are equal and opposite the system is stable and does not cause the cell to burst or shrink.
So, the correct answer is option A.
