Answer:

Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four cells.

Explanation:

Mitosis  

  • Results in two daughter cells
  • Results in diploid daughter cells chromosome number remains the same as parent cell
  • Daughter cells are genetically identical
  • Occurs in all organisms except viruses
  • Creates all body cells (somatic) apart from the germ cells (eggs and sperm)
  • Prophase is much shorter
  • No recombination/crossing over occurs in prophase.
  •  In metaphase individual chromosomes (pairs of chromatids) line up along the equator.
  • During anaphase the sister chromatids are separated to opposite poles.

Meiosis

  • Involves two successive cell divisions
  • Results in four daughter cells
  • Results in haploid daughter cells (chromosome number is halved from the parent cell)
  • Daughter cells are genetically different
  • Occurs only in animals, plants and fungi
  • Creates germ cells (eggs and sperm) only
  •  Prophase I takes much longer
  • Involves recombination/crossing over of chromosomes in prophase I
  • In metaphase I pairs of chromosomes line up along the equator.
  • During anaphase I the sister chromatids move together to the same pole.
  • During anaphase II the sister chromatids are separated to opposite poles.
