Vedclass · Answer

(A) In the development of the male gametophyte in angiosperms,the pollen grain undergoes mitosis to form a large vegetative (tube) cell and a small generative cell.Initially,the generative cell is surrounded by a callose wall. As the pollen grain matures,this wall dissolves,allowing the generative cell to detach and float freely within the cytoplasm of the vegetative cell.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for why the generative cell lies freely in the cytoplasm.

$A$: The generative cell comes to lie freely in the cytoplasm of the tube cell.
$R$: The cellulosic wall around the generative cell is dissolved.
