  • Cleavage is the series of rapid mitotic divisions in zygote and forms blastula. The 2, 4, 8, 16 daughter cells are called blastomere. Embryo with 64 blastomere is known as blastocyst and has blastocoel cavity. Blastocyst gets implanted in uterine wall and leads to pregnancy. Solid mass of cells with 16 blastomere is called:

    A
    Morula
    B
    Blastula
    C
    Gastrula
    D
    Zygote
