Question:
How does the cleavage differ from mitosis?
Options:
It lacks synthetic phase
It lacks growth phase.
Both A and B .
None of these.
Correct Answer:
It lacks growth phase.
Explanation:
Cleavage is a series of rapid mitotic divisions of the zygote, during cleavage there are no intervening growth periods between the successive divisions. Therefore the cells get smaller & smaller, but the embryonic mass remains essentially the same size whereas normal Mitosis occurs in most of somatic cells for a longer period and daughter cells formed go to growth phase.
