Given below are two statement:
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:
Both A and R are true and R is the correct explanation of A
Both A and R are true but R is NOT the correct explanation of A.
A is true but R is false.
A is false but R is true.
Answers (1)
The correct answer is Option 3) A is true but R is false.
Assertion A is true. Gymnosperms are plants that produce naked seeds, and their pollen grains are typically released from the microsporangium (pollen sacs) and are dispersed by air currents. This is known as anemophily, which is a common mode of pollination in gymnosperms.
Reason R is false. Air currents do carry the pollen grains, but they are not specifically directed to the mouth of the archegonia. In gymnosperms, the male gametes are discharged from the pollen grains and are transported to the female reproductive structures called ovules. The male gametes typically travel through a pollen tube to reach the archegonia, where fertilization takes place.
Therefore, while Assertion A is true, Reason R is incorrect as it does not provide a correct explanation for Assertion A.
