A) meiosis
B) mitosis
C) cleavage
D) differentiation
Correct Answer: C
Solution :
Cleavage is a series of rapid mitotic divisions of the zygote which converts the single celled zygote into a multicellular structure called blastula. The cleavage divisions are no doubt mitotic as they produce diploid cells but they differ from typical mitosis in the following manner :| Characters | Cleavage | Normal mitosis |
| Site of occurrence | In zygote of parthenogenetic egg | In most of somatic cells |
| Interphase | of shorter period | of longer period |
| Growth | Does not occur | Occurs during interphase |
| Oxygen consumption size of daughter cells | High as is very rapid process Decreases | Low as is slow process |
| DNA synthesis | Faster | Slower |
| Nuclear cytoplasmic ratio | Increases | Remains same |
