The difference between mitosis and meiosis are as follow:
Differences between mitosis and meiosis
| Term | Mitosis | Meiosis |
| Definition | In cell biology, The process by which a cell replicates its chromosomes and then segregates them, producing two identical nuclei in preparation for cell division. | A type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. |
| Cell divisions | In Mitosis, One cell division | In Meiosis, Two cell divisions |
| Mode of Reproduction | Asexual Reproduction | Sexual Reproduction |
| Function | General growth and repair, Cell reproduction | Genetic diversity through sexual reproduction |
| Daughter cells | Produces two daughter cells | Produces four daughter cells |
| Produces cells | Produces diploid cells | Produces haploid cells |
| Prophase | Prophase is much shorter | Prophase I takes much longer |
| Metaphase | Individual chromosomes (pairs of chromatids) line up along the equator. | Pairs of chromosomes line up along the equator. |
| Anaphase | During anaphase, the sister chromatids are separated into opposite poles. | During anaphase, the sister chromatids move together to the same pole. |
| Occurs | Occurs in all organisms except viruses | Occurs only in animals, plants and fungi |
| Occurrence | All the cells | Reproductive cells |
Mitosis Overview
In a unicellular organism, the purpose of mitosis is to proliferate as a species. In a multicellular organism, the purpose can be to grow during development or to repair or regenerate damaged tissue. Two diploid cells with identical genetic information. In mitosis, the nuclear membrane is broken down, and spindle fibers (microtubules) attach to the chromatids at the centromere and pull apart the chromatids. It consists of interphase, prophase, metaphase, anaphase, and telophase. Each nucleus is identical to the original nucleus as it was in G1,
Meiosis Overview
Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms used to produce the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome. In humans, this means the chromosome number is reduced from 46 to 23. Meiosis consists of meiosis I and meiosis II. In meiosis I homologous chromosomes are separated into different nuclei. As in mitosis, it is spindle fibres that “pull” the chromosomes and chromatids apart.
Phases of Mitosis and Meiosis
Meiosis and mitosis both have a prophase, metaphase, anaphase, telophase and cytokinesis.
Similarities between mitosis and meiosis
The similarities between mitosis and meiosis are as follow:
- Mitosis and meiosis take place in the cell nuclei.
- Both involve cell division.
- Both the processes occur in the M-phase of the cell cycle.
- In both cycles, the stages are common – metaphase, anaphase, telophase, and prophase.
- Synthesis of DNA occurs in both.
What is Mitosis and Meiosis ?
Mitosis: In a unicellular organism, the purpose of mitosis is to proliferate as a species. In a multicellular organism, the purpose can be to grow during development or to repair or regenerate damaged tissue.
Meiosis: Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms used to produce the gametes, such as sperm or egg cells.
What are the phases of Mitosis & Meiosis ?
The phases of mitosis & meiosis are prophase, metaphase, anaphase, telophase and cytokinesis.
How do cells divide?
The cell division mitosis and meiosis, mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells.
What is difference between mitosis and meiosis?
Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
What are the 4 major difference between mitosis and meiosis?
Mitosis: Asexual Reproduction, Produces two daughter cells, Produces diploid cells, Occurs in all organisms except viruses.
Meiosis: Sexual Reproduction, Produces four daughter cells, Produces haploid cells, Occurs only in animals, plants and fungi.
What is the difference between mitosis and meiosis during metaphase?
In mitosis, Individual chromosomes (pairs of chromatids) line up along the equator and In meiosis, Pairs of chromosomes line up along the equator.
What are the mitosis and meiosis similarities ?
The Similarities between mitosis and meiosis are as follow:
1. Mitosis and meiosis take place in the cell nuclei.
2. Both involve cell division.
3. Both processes occur in the M-phase of the cell cycle.
4. In both cycles, the stages are common – metaphase, anaphase, telophase, and prophase.
Synthesis of DNA occurs in both.
