Cleavage differs from normal mitotic divisions as
Cleavage differs from normal mitotic divisions as
Options
- AThere is no nuclear division during cleavage.
- BThere is no division of cytoplasm during cleavage.
- CThere is no growth phase between the cleavages.
- DThe division of cytoplasm follows nuclear division.
Correct answer
C. There is no growth phase between the cleavages.
Step-by-step solution
Cleavage is a series of rapid mitotic divisions of the zygote characterized by the absence of growth phases (G1 and G2 phases) between successive divisions.
Due to the lack of a growth phase, the total volume or size of the embryo remains constant, while the number of cells increases and the size of individual cells (blastomeres) decreases.
In normal mitotic divisions, a distinct growth phase occurs where the cell grows to its original size before undergoing the next division.
Answer: There is no growth phase between the cleavages.
