Directions: In the following questions, a statement of assertion (A) ...
Assertion: Pollen grains from the carpel stick to the stigma of stamen.
Reason: The fertilised egg cells grow inside the ovules and become seeds.
To answer this question, we need to evaluate the validity of both the assertion and the reason provided.
Assertion Evaluation:
The assertion states that pollen grains from the carpel stick to the stigma of the stamen. This is true. Pollination is the transfer of pollen grains from the anther (part of the stamen) to the stigma (part of the carpel). This process can occur through self-pollination or cross-pollination.
Reason Evaluation:
The reason states that the fertilized egg cells grow inside the ovules and become seeds. This is also true. After pollination, the pollen grains germinate on the stigma and produce a pollen tube. This pollen tube grows down through the style and reaches the ovary, where the ovules are located. Fertilization occurs when the pollen tube releases male gametes that fuse with the female gametes in the ovules. These fertilized egg cells then develop into seeds.
Conclusion:
Both the assertion and reason are true. However, the reason does not provide a correct explanation for the assertion. The reason explains the process of fertilization and seed formation, but it does not directly explain why pollen grains from the carpel stick to the stigma of the stamen. Therefore, the correct answer is option 'b' - Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
