Answer 2

Answer:

Both assertion and reason are true and the reason is the correct explanation of the assertion.

Explanation:

• The cells that have cell walls withstand hypotonic external media without bursting.
• We know that the cells of plants, fungi, as well as of bacteria are surrounded by rigid cell walls.
• These cell walls easily let them take up water through the process of osmosis when they are put in any hypotonic medium, or in other words, the medium that is more dilute in comparison to their internal environments.
• Because of the presence of a cell wall, these cells can easily tolerate high internal pressure as a result of which they can swell up but they will certainly not burst.

Final Answer:

Assertion: Cells having the cell wall withstand very dilute (hypotonic) external media without bursting.

Reason: The cell wall exerts equal pressure against the swollen cell.

• Both assertion and reason are true and the reason is the correct explanation of the assertion.
