Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R): Assertion (A): In gymnosperms, the pollen grains are released from the microsporangium and carried by air currents. Reason (R): Air currents carry the pollen grains to the mouth of the archegonia where the male gametes are discharged and pollen tube is not formed. In the light of the above statements, choose the correct answer from the options given below:
(A) is False, (R) is True.
Both (A) and (R) are True and (R) correctly explains (A).
Both (A) and (R) are True and (R) does not correctly explain (A).
(A) is True, (R) is False.
in gymnosperms, the pollen grains are released from the microsporangium and are carried by air currents to come in contact with the opening of the ovules . However, the Reason (R) is incorrect because the text explicitly states that 'The pollen tube carrying the male gametes grows towards archegonia in the ovules and discharge their contents near the mouth of the archegonia' . Therefore, a pollen tube is formed, contrary to the claim in the Reason.
