Assertion: Autogamy is a transfer of pollen grains from an anther to the stigma of the same flower on the same plant.
Reason: Xenogamy is pollination between two flowers on different plants.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Both Assertion (A) and Reason (R) are correct, but R is not the correct explanation of A.
Explanation:
Assertion (A) is correct:
- Autogamy is a type of self-pollination, where pollen grains from the anther are transferred to the stigma of the same flower.
Reason (R) is also correct:
- Xenogamy is a type of cross-pollination where pollen is transferred between flowers of different plants of the same species.
However, Reason (R) is not the explanation for Assertion (A):
- The definition of xenogamy does not explain autogamy.
- To explain autogamy, a correct reason would be:
- "Autogamy ensures reproductive success even in the absence of pollinators and maintains genetic purity."
Final Answer:
Both Assertion (A) and Reason (R) are correct, but R is not the correct explanation of A.
