What are the differences between cleavage and mitosis?
Posted November 30, 2023
Basis of differentiation |
Cleavage |
Mitosis |
Definition |
Cleavage is the initial division of the parent cytoplasm into cytoplasms of 2 daughter cells |
Mitosis is a type of cell division which results in 2 genetically identical daughter cells from the parent nucleus |
Occurrence |
Occurs only in animal cells (in the zygote) |
Occurs in animal and plant cells |
Growth |
Growth does not occur |
Growth occurs during interphase |
Oxygen consumption |
Oxygen consumption is high |
Oxygen consumption is low |
Result |
Cleavage ends with the formation of a blastocyst |
Mitosis results in 2 genetically identical daughter cells |
Size of end products |
Size of blastomeres decreases as their number increases |
Size of the daughter cells remain constant |
DNA synthesis |
DNA synthesis occurs at a much higher rate to produce chromosomes for blastomeres |
DNA synthesis occurs at normal speeds |
Interphase |
Interphase is short (due to the modified cell cycle without G1 and G2 phases) and blastomeres do not grow during this phase |
Interphase is long and daughter cells grow during this phase |
