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.
