Question

Assertion: The same plant can have different shapes of leaves.
Reason: Plants follow different pathways in response to the environment or phases of life to form different kinds of structures.

Select the correct option from below:

• A. If both assertion and reason are true and the reason is the correct explanation of the assertion
• B. If both assertion and reason are true but the reason is not the correct explanation of the assertion
• C. The assertion is true but the reason is false
• D. Both assertion and reason are false

Answer 1

The correct option is A If both assertion and reason are true and the reason is the correct explanation of the assertion

Heterophylly is a phenomenon in which plants can have different leaf shapes in various environmental conditions or phases of life. For example - in larkspur, juvenile phase leaves bear a different shape than that of the mature phase. Hence, the assertion is correct.

The ability of plants to follow different pathways to observe different pathways as a response to different environmental conditions or phases of life to develop various kinds of structures is called plasticity. Plasticity helps the plant to survive. Heterophylly is a case of plasticity. Hence, the reason is true and it correctly explains the assertion.
