Vedclass · Answer

(C) In $Spirogyra$,sexual reproduction occurs through conjugation. During the process of conjugation,the protoplast of the vegetative cells acts as a gamete. Before the fusion of these gametes (conjugation),the protoplast of the vegetative cell undergoes contraction and rounds up to form a gamete. Therefore,the contraction of the protoplast occurs just before the fusion of gametes.
