Question

Cleavage brings about

• A. The distribution of the cytoplasm of the zygote, amongst the blastomeres
• B. Increased mobility of the protoplasm, which facilitates morphogenetic movements necessary for cell differentiation, germ layer formation and the formation of tissue and organs
• C. Unicellular zygote is converted into multicellular embryo
• D. All of the above

Answer 1

Answer: (D)

All of the above

Cleavage is the process of division of a unicellular zygote into a multicellular embryo. It brings about the distribution of the cytoplasm of the zygote, amongst the blastomeres. It also enables increased mobility of the protoplasm, which facilitates morphogenetic movements necessary for cell differentiation, germ layer formation, and the formation of tissue and organs.

So, the correct answer is 'All of the above'.
