Study Notes
Shared Characteristics of Mitosis and Meiosis
- Both produce new cells
- Both require a parent cell
- Both follow the same steps for cell division: prophase, metaphase, anaphase, telophase
- Both involve the duplication of chromosomes
- Both involve the breakdown of the nuclear membrane
Mitosis
- A process of asexual reproduction that produces a replica with an equal number of chromosomes in each resulting diploid cell
- Creates normal body cells (everything other than sex cells)
- Occurs in both sexually and asexually reproducing organisms
- Function: cellular reproduction and general growth and repair of the body
- Genetically: identical
- Produces 2 diploid cells
- Chromosome number: remains the same
- Number of divisions: 1 cell division
- Stages: prophase, metaphase, anaphase, telophase
Meiosis
- A type of cellular reproduction that reduces the number of chromosomes by half, producing two haploid cells
- Creates sex cells only: female egg cells or male sperm cells
- Occurs in sexually reproducing organisms only
- Function: genetic diversity through sexual reproduction
- Genetically: different
- Produces 4 haploid cells
- Chromosome number: reduced by half
- Number of divisions: 2 cell divisions (meiosis 1 and meiosis 2)
- Stages: prophase I, metaphase I, anaphase I, telophase I; prophase II, metaphase II, anaphase II, and telophase II
Mitosis vs Meiosis
Definition and Purpose
- Mitosis: a process of asexual reproduction, resulting in two diploid cells with an equal number of chromosomes.
- Meiosis: a type of cellular reproduction, reducing the number of chromosomes by half, producing two haploid cells.
Cell Types and Occurrence
- Mitosis: creates normal body cells (except sex cells), occurs in both sexually and asexually reproducing organisms.
- Meiosis: creates sex cells only (female egg cells or male sperm cells), occurs in sexually reproducing organisms only.
Function and Genetic Diversity
- Mitosis: cellular reproduction, general growth, and repair of the body, producing identical cells.
- Meiosis: genetic diversity through sexual reproduction, producing different cells.
Cell Division and Chromosome Number
- Mitosis: 2 diploid cells produced, chromosome number remains the same, one cell division.
- Meiosis: 4 haploid cells produced, chromosome number reduced by half, two cell divisions (Meiosis 1 and Meiosis 2).
Stages of Cell Division
- Mitosis: Prophase, Metaphase, Anaphase, Telophase.
- Meiosis:
- Meiosis 1: Prophase I, Metaphase I, Anaphase I, Telophase I.
- Meiosis 2: Prophase II, Metaphase II, Anaphase II, Telophase II.
