Question

diffrentiate with full defination

mitiosis and meiosis

Answer 1

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.
