Question

Assertion: Cell place in a hypertonic solution shows plasmolysis

Reason: Not all cell shows plasmolysi​

Answer 1

Answer:

The behaviour of the plant cells or tissues with regard to water movement depends on the surrounding solution. When the cell or tissue is placed in a hypertonic solution, water moves out; it is first lost from the cytoplasm and then from the vacuole. The water when drawn out of the cell through diffusion into the extracellular(outside cell) fluid causes the protoplast to shrink away from the walls. The cell is said to be plasmolysed.

So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
