What are the two types of cell division?
Answer
The two types of cell division are mitosis and meiosis. Mitosis is responsible for making new somatic cells (every body cell except sex cells). Meiosis is the type of cell division that creates sex cells (egg and sperm cells). Cell division is a fundamental process for life.
Mitosis Meiosis
Involves one cell division: PMAT Involves two successive cell divisions: PMAT and PII, MII, AII, and TII
Results in two daughter cells Results in four daughter cells
Results in diploid daughter cells (chromosome Results in haploid daughter cells (chromosome is halved from the
remains the same as the parent cell parent cell)
Daughter cells are genetically identical Daughter cells are genetically different
Occurs in all organisms except viruses Occurs only in animals, plants, and fungi
Create all body cells (somatic cells) Create sex cells (egg and sperm only)
No recombination or crossing over occurs Involves recombination/ crossing over in prophase I
In metaphase pairs of chromatids line up at In metaphase I pairs of chromosomes line up at the equator
the equator
During anaphase sister chromatids are During anaphase I chromosomes are drawn to the same poles
separated to opposite poles During anaphase II sister chromatids are separated to opposite poles
