what is the difference between meiosis and mitosis
plz answer do
Answers
Mitosis is the division of body cells and meiosis is the division of the sex cells.
Explanation:
Mitosis
1) This division takes place in somatic cells and as a result of this growth occurs.
2) Completed in one stage.
3) Prophase is smaller (when compared to prophase of Meiosis).
4) No crossing over takes place.
5) Synapsis does not take place at metaphase.
6) At metaphase, centromere is towards equatorial plate and ends of chromosomes towards poles. Centromere divides.
7) Chromatids are long and thin.
8) Cytokinesis follows karyokinesis.
Meiosis
1) It takes place in reproductive cells
2) Completed in two stages.
3) Prophase longer than prophase of mitosis and divided into five substages.
4) Crossing over takes place in which exchange of segments of chromatids occurs.
5) Synapsis between homologous chromosomes takes place (bivalent stage).
6) At metaphase I, the centromere is towards poles and ends of chromosomes towards equatorial plate. Centromere does not divide.
7) Chromatids are shorter and thick
8) After Telophase I, cytokinesis does not takes place always.

Answer:
Meiosis and Mitosis are important phase of cell division.
Explanation:
Both are part of cell division but they are different from each other. Some of the differences between meiosis and mitosis are as following:
Meiosis:
- Meiosis produces genetically different sex cells that will be used to create an entirely new organism.
- There are two cell divisions in meiosis and cell undergoes each phase two times.
- Crossing over or recombination of chromosomes take place in meiosis during prophase I.
- Four daughter cells are produced as the end result.
- It creates haploid daughter cells.
Mitosis:
- Mitosis produces identical copies which replaces body cells.
- There is only one cell division in mitosis, so the cell goes through each phase only once.
- No crossing over or recombination of chromosomes take place in mitosis.
- Two daughter cells are produced as end result.
- It creates diploid daughter cells.
