Definition:

“The type of cell division in which a cell divides into two daughter cells, each with the same number of chromosomes as were present in the parent cell is called mitosis.”

Discovery:

In the 1880s, German biologist Walther Fleming observed that in a dividing cell, the nucleus passes through a series of changes which he called mitosis.

Occurrence:

  •   Mitosis occurs only in eukaryotic cells.
  •  In multicellular organisms, the somatic cells undergo mitosis. 

The process of mitosis is divided into two major phases.

Karyokinesis:

  The division of the nucleus known as karyokinesis is divided into four phases.

  1. Prophase. 
  2. Metaphase.
  3. Anaphase.
  4. Telophase.

Cytokinesis:

  The division of cytoplasm is known as cytokinesis.
