Answers (1)
Embryonic Development: Cleavage & Formation of Blastocyst -
- The mitotic division starts as the zygote moves through the isthmus of the oviduct called cleavage towards the uterus and forms 2, 4, 8, 16 daughter cells called blastomeres.
- When the blastomeres divide completely the cleavage is called holoblastic cleavage..
- Also, In mammals, the zygote divides into equal blastomeres and thus, cleavage is called holoblastic equal.
Significance of Cleavage:
- Cleavage distributes the cytoplasm of the zygote amongst the blastomeres.
- It allows for morphogenetic movements necessary for cell differentiation, germ layer formation and tissue and organ formation.
- It converts the unicellular zygote into a multicellular organism
Hence the correct option is (a).
