QUESTION
Fertilized ovum is divided into number of cells by mitotic division by the process of?
OPTIONS
(A) Bastulation
(B) Cleavage
(C) Gastrulation
(D) None of these
ANSWER
(B) Cleavage
EXPLANATION
Cleavage is the correct option because cleavage is the series of rapid mitotic divisions by which a fertilized ovum becomes a multicellular embryo without a corresponding increase in overall embryonic size. Gastrulation is the later process of germ-layer formation, while “bastulation” is not the standard term for these early mitotic divisions.
