Read the given statements and select the correct option.Statement 1 : ...
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.

Read the given statements and select the correct option.Statement 1 : ...
Statement 1: Plant cells do not rupture when placed in distilled water.
Plant cells have a rigid cell wall surrounding the cell membrane. This cell wall provides structural support and prevents the cell from bursting or rupturing when placed in a hypotonic solution like distilled water. The cell wall exerts an inward pressure on the cell membrane, counteracting the osmotic pressure created by the water entering the cell. As a result, the cell remains intact and does not rupture.
Statement 2: Animal cells rupture when placed in distilled water.
Unlike plant cells, animal cells do not have a rigid cell wall. Instead, they have a flexible cell membrane that regulates the movement of substances in and out of the cell. When placed in a hypotonic solution like distilled water, water molecules move into the animal cell through osmosis. As water enters the cell, the cell swells and eventually bursts, leading to the rupture of the animal cell.
Explanation:
Both statements 1 and 2 are correct, but statement 2 is not the correct explanation of statement 1. While statement 1 correctly states that plant cells do not rupture when placed in distilled water due to the presence of a rigid cell wall, statement 2 incorrectly implies that animal cells rupture in distilled water for the same reason. Animal cells rupture in distilled water because they lack a cell wall, not because they have one like plant cells.
Therefore, the correct option is B: Both statements 1 and 2 are correct, but statement 2 is not the correct explanation of statement 1.
