Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Meristemoids are individual cells that are responsible for the differentiation of distinct structures. Reason (R): The microspore divides into a larger vegetative cell and a smaller generative cell. In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Ensure each statement is evaluated independently and their relationship is correctly understood.

Answer 1

The Correct Option is B

Step 1: Concept
Plant cell division and differentiation

Step 2: Meaning
Understanding the roles of meristemoids in plant development and the process of microspore division.

Step 3: Analysis
Statement A correctly identifies that meristemoids are individual cells responsible for the formation of distinct structures through differentiation. However, Statement R describes a specific process related to the development of pollen grains rather than meristemoids.

Step 4: Conclusion
Both statements are correct, but Reason (R) does not explain Assertion (A). Final Answer: (B)
