Given below are two statements. One is labeled Assertion(A) and the other is labeled Reason(R).Assertion: Sexual reproduction in Volvox takes place by oogamy.Reason: Volvox shows fusion between smaller motile, flagellated male gamete and larger, flagellated female gamete.

Assertion (A): Sexual reproduction in Ulothrix and Spirogyra is oogamous.Reason (R) : Male and female gametes are flagellated and similar in size (as in Ulothrix) or non flagellated (non motile) but similar in size (as in Spirogyra). Both (A) & (R) are correct but (R) is not the correct explanation of (A).(A) is correct but (R) is not correct.(A) is not correct but (R) is correct.Both (A) & (R) are correct and (R) is the correct explanation of (A).

Assertion (A) - Birds are oviparous animals.Reason (R) - Birds show external fertilization.(a) Both A and R are true and R is the correct explanation of A.(b) Both A and R are true but R is not the correct explanation of A.(c) A is true but R is false.(d) A is false but R is true

Assertion :- Sexual reproduction of Spirogyra is isogamous type.Reason :- Both of the fusing gametes of Spirogyra are nonflagellated and similar in size.Both Assertion and Reason are true and Reason is the correct explanation of Assertion.Both Assertion and Reason are true but Reason is not correct explanation of Assertion.Assertion is true but Reason is false.Assertion is false but Reason is true.

Assertion : Pollen mother cells (PMCs) are the first male gametophytic cells..Reason : Each PMC gives rise to two pollens..(a) Both A and R are true and R is the correct explanation of A.(b) Both A and R are true but R is not the correct explanation of A.(c) A is true but R is false.(d) Both A & R are false
