    What is true for cleavage?

    A)  Size of embryo increases

    B)  Size of cells decreases

    C)  Size of cells increases

    D)  Size of embryo decreases

    Correct Answer: B

    Solution :

    Cleavage is a succession of rapid cell division during which the cells undergo the S (DNA synthesis) and M .(mitosis) phases of the cell cyle but often virtually skip the \[{{G}_{1}}\] and \[{{G}_{2}}\] phases. Cleavage simply divides the cytoplasm of larger cells into smaller cells, called blastomeres.
