Vedclass · Answer

(A) During the process of cleavage,the zygote undergoes repeated mitotic divisions to form a solid ball of cells called the morula. As the number of cells increases,the size of individual cells (blastomeres) decreases because there is no growth phase ($G_1$ or $G_2$) between these divisions. Therefore,the overall size of the embryo remains constant while the cell size decreases.
