Sexual Reproduction in Flowering Plants

Question:

Assertion: Rhizomes, tubers and corms are excellent methods of sexual reproduction.
Reason: Autogamy is transfer of pollen from anther of one flower to stigma of another.

Options:

Both Assertion (A) and Reason (R) are correct and R is the correct explanation of A.

Both Assertion (A) and Reason (R) are correct and but R is not the correct explanation of A.

Assertion (A) is true but Reason (R) is not correct.

Both Assertion (A) and Reason are false (F ).

Correct Answer:

Both Assertion (A) and Reason are false (F ).

Explanation:

The correct answer is Option (4) → Both Assertion (A) and Reason (R) are false.

Explanation:

Assertion: "Rhizomes, tubers, and corms are excellent methods of sexual reproduction."False

  • Rhizomes, tubers, and corms are modified underground stems that help in vegetative propagation, which is a form of asexual reproduction, not sexual reproduction.
  • Sexual reproduction involves fusion of gametes, whereas vegetative propagation produces offspring without fertilization.

Reason: "Autogamy is the transfer of pollen from the anther of one flower to the stigma of another."False

  • Autogamy refers to self-pollination within the same flower (not between different flowers).
  • The correct term for pollen transfer between flowers of the same plant is geitonogamy, while transfer between flowers of different plants is xenogamy.

Final Answer:

Both Assertion (A) and Reason (R) are false.
