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 gametes are discharged and pollen tube is not formed.In the light of the above statements, choose the correct answer:

  1. A
    Both A and R are true and R is the correct explanation of A
  2. B
    Both A and R are true but R is NOT the correct explanation of A
  3. C
    A is true but R is false
  4. D
    A is not false but R is true

Solution & Step-by-step Explanation

Assertion A is correct: Gymnosperms are wind-pollinated; pollen is released from microsporangia and travels by air.Reason R is false: While air carries pollen to the ovule, the pollen grain does form a pollen tube (siphonogamy) which grows toward the archegonia to discharge the male gametes.
