NEET (UG) 2023 — Question 107
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 light of the above statements, choose the most appropriate answer from the options given below.er from the options given below :
- Option A:
Both (A) and (R) are true and (R) is the correct explanation of (A).
- Option B:
Both (A) and (R) are true and (R) is NOT the correct explanation of (A).
- Option C:Correct
(A) is true but (R) is false.
- Option D:
(A) is false but (R) is true.
Answer: C
Step-by-step solution
Assertion (A) is true: in gymnosperms, pollen grains are released from microsporangia and dispersed by wind. Reason (R) is false: pollen grains are carried to the ovule (micropyle), not directly to the mouth of archegonia; a pollen tube is formed that carries male gametes to the archegonia. Therefore, (A) is true but (R) is false.
