Vedclass · Answer

(A) In $Chara$,the plant body is monoecious,meaning both male (antheridium) and female (oogonium) sex organs are present on the same plant.However,$Chara$ exhibits a condition known as protandry,where the male sex organs (antheridia) mature earlier than the female sex organs (oogonia).Because the male gametes are released before the female gametes are ready for fertilization,self-fertilization is prevented,and the plant undergoes cross-fertilization.Therefore,both the Assertion and the Reason are correct,and the Reason is the correct explanation for the Assertion.

$A$: Most of the species of $Chara$ are monoecious but show cross-fertilization.
$R$: The plant body shows protandrous condition.
