Mitosis and Meiosis

Biology Mrs. Sims by Alexandra Wall

How are mitosis and meiosis similar?

  • Mitosis and Meiosis are both forms of reproduction.
  • They both go through Prophase, Metaphase, Anaphase, and Telophase.
  • They both start with a Diploid parent cell.
  • Both end with cytokinesis.
  • In metaphase individual chromosomes line up along the equator.

How are Mitosis and Meiosis Different?

Mitosis-

  • Involves only one cell division.
  • Results in two daughter cells.
  • Daughter cells are genetically identical.
  • Occurs in all cells except in viruses.
  • Creates all body cells except sex cells.
  • Prophase is shorter.
  • In metaphase individual chromosomes line up along the equator.

Meiosis-

  • Involves two successive cell divisions.
  • Results in four daughter cells.
  • Daughter cells are genetically different.
  • Occurs only in plants, animals, and fungi.
  • Creates only sex cells.
  • Prophase 1 takes much longer.
  • In metaphase 1 pairs of chromosomes line up along the chromosomes.

Why is Mitosis and Meiosis important to living things?

The importance of Mitosis and Meiosis

  • In mitosis cells generate new cells.
  • Without this ability the species would die because the organisms require cells to live.
  • The meiosis process allows the organism to produce sex cells.
  • Without meiosis the species would die out because they would not be able to reproduce.
  • Mitosis also allows for genetic stability.

How are Mitosis and Meiosis related to asexual and sexual production?

  • Mitosis is no related to sexual reproduction; however, meiosis is.
  • Even though meiosis is related to sexual reproduction is only occurs in gametes.
  • The resulting daughter cells have different genetic information than their parent cells.
  • This method of reproductions is important in the continuation of the specie when the environmental conditions change.
  • Meiosis is not related to asexual reproduction.
  • Mitosis is related because the cells are exactly the same.
