Cell Division by Mitosis | All stages of mitotic cell division

Mitosis :

• Mitosis occurs continuously inside the body or somatic cells.
• The nucleus divides only once.
• They follow the asexual mode of reproduction that is found in somatic cells.
• It occurs more frequently.
• It is always an equational division.
• Daughter cells have a diploid number (2N) of chromosomes like their parent plant.
• The whole process complete in one sequence or phase after one round of DNA replication.
• No crossing over or chiasmata formation takes place in the chromosome.
• There is no exchange of genetic material between the homologous chromosome.
• It has some sub-phase for different functions regarding cell division.

Interphase:

-They contain 23 pairs of chromosome i.e., 46 chromosomes (n).

Prophase:

-Chromosome doubled to 92 and then the nucleus dissolves and microtubules attach to the nucleus(2n).

Metaphase:

-Chromosome aligns in the middle of the cell or the equator.

Anaphase:

-Separated chromosome pulled apart from the center after being attached to centromere with the help of spindle fiber.

Telophase:

-Microtubules disappear and cell division begins.

Cytokinesis:

-The daughter cells are formed with 46 each chromosome, equal to the parent cell.

• There is only one prophase, one metaphase, one anaphase, and one telophase.
• Two identical daughter cells are formed.
