Difference between cleavage and mitosis

Main difference

The main difference between division and mitosis is that division is cytoplasmic division that follows nuclear division, while mitosis is the process of cell division in which the stem cell divides into two daughter cells …

Excision versus mitosis

Mitosis and cleavage are the two events of the cell cycle. Cleavage is also known as cytokinesis, while the two steps of mitosis include karyokinesis and cytokinesis. Cleavage is the cytoplasmic division that follows nuclear division. Mitosis, on the other hand, is the process of cell division in which the mother cell divides into two daughter cells. Basically, cleavage is the second step of cell division and is responsible for the division of the stem cell into two daughter cells. Cleavage begins during telophase, which is the final stage of nuclear division.In addition, cytokinesis is the term that describes the cytoplasmic division of all cell types, including plant cells, animal cells and prokaryotic cells because the cleavage process is primarily concerned with cytokinesis in animals. Rather, the mitosis process occurs through two steps; nuclear division, which follows cytokinesis. The process of cytokinesis in an animal, as well as in many single-celled eukaryotes, occurs through four steps, including initiation, contraction, membrane insertion, and termination. Mitosis, on the other hand, also has four stages that include prophase, metaphase, anaphase, and telophase. membrane insertion and completion. Mitosis, on the other hand, also has four stages including prophase, metaphase, anaphase, and telophase. membrane insertion and completion. Mitosis, on the other hand, also has four stages including prophase, metaphase, anaphase, and telophase.

Comparative chart

Neckline Mitosis
The cytoplasmic division that follows nuclear division is called cleavage. The process of cell division in which the mother cell divides into two daughter cells is called mitosis.
Idea
Cleavage occurs only in animal cells. Mitosis occurs in both plant and animal cells.
Meaning
The cleavage is also known as cytokinesis in animal cells. There are two steps of mitosis, which are karyokinesis and cytokinesis.
Events (edit)
During cleavage, division of the stem cell’s cytoplasm occurs in the two daughter nuclei. During mitosis, the division of the parent nucleus occurs in the two daughter nuclei and then the division of the cytoplasm occurs.
Components
Components such as myosin filaments, actin filaments, and the contractile ring are involved in cleavage. Mitotic spindles that are made up of microtubules are involved in nuclear division.
In Embryology
Excision suggests rapid cell division of the zygote by mitosis. Mitosis is that type of cell division responsible for excision.
Size
The size of the blastomere decreases as its number increases. The size of the daughter cells remains almost constant during growth.
Presence
Cleavage occurs in the parthenogenetic cell or in the zygote. Mitosis occurs in most cells in the body.
Cytoplasmic or nuclear relationship
The cytoplasmic or nuclear ratio increases as cleavage progresses. The cytoplasmic or nuclear ratio does not change during mitosis.
Consequence
The division follows the nuclear division. Mitosis is followed by cytokinesis, which in turn is followed by division of the cytoplasm.
What is cleavage ?

Cleavage is the cytoplasmic division that follows nuclear division. During embryogenesis, cleavage suggests rapid mitotic divisions of the zygote and forms the blastocyst, which is a multicellular structure. As the cleavage is involved in the dispersion of the cytoplasm of the zygote between the cells of the blastocyst, it is characterized by the lack of growth of daughter cells. The cytokinesis process in an animal, as well as in many single-celled eukaryotes, occurs through all four steps, which are initiation, contraction, membrane insertion, and termination.

What is mitosis ?

Mitosis is cell division in which the mother cell divides into two daughter cells. It is a cell cycle event that follows the G 2 phase . The mitosis process occurs through two steps; nuclear division, which follows cytokinesis. It is responsible for asexual reproduction as it produces new cells, which can replace damaged, old or lost cells. Also, the daughter cells that are produced by mitosis have the exact number of chromosomes as the parent cell. The process of mitosis includes four stages, which are prophase, metaphase, anaphase, and telophase.

Key differences

  1. The cytoplasmic division that follows nuclear division is called excision, while the process of cell division in which the mother cell divides into two daughter cells is called mitosis.
  2. The size of the blastomere decreases as its number increases, while the size of the daughter cells remains almost constant during growth.
  3. Cleavage is the process that occurs only in animal cells; on the other hand, mitosis is the process that occurs in both plant and animal cells.
  4. Cleavage is the process that is also known as cytokinesis in animal cells. Rather, there are two steps of mitosis, which are karyokinesis and cytokinesis.
  5. During the excision process, the division of the mother cell’s cytoplasm occurs in the two daughter nuclei, on the other hand, during the mitosis process, the division of the father nucleus occurs in the two daughter nuclei and then the division of occurs the cytoplasm.
  6. Components such as myosin filaments, actin filaments and the contractile ring are involved in the cleavage process, on the other hand, the mitotic spindle that is made up of microtubules is involved in nuclear division.
  7. Excision is the process that suggests the rapid cell division of the zygote by mitosis, on the other hand, mitosis is that type of cell division that is responsible for excision.
  8. Cleavage follows nuclear division, on the other hand, mitosis is followed by cytokinesis, which is the stage of cell division and oversees the separation of identical genetic material into the two new nuclei and is followed by division of the cytoplasm.
  9. The cytoplasmic or nuclear ratio increases as cleavage progresses, whereas the cytoplasmic or nuclear ratio does not change during mitosis.
  10. Cleavage occurs in the parthenogenetic or zygote cell, while mitosis occurs in most cells in the body.
Final Thought

All of the above discussion sums up that cleavage is the cytokinesis of animal cells. It comprises the division of the cytoplasm between the two daughter nuclei that were formed during nuclear division. Mitosis, on the other hand, is the division of a stem cell into two daughter cells that contain the same number of chromosomes as was present in the stem cell.
