What is mitosis?
What is mitosis?
Mitosis is the process of cell division for somatic or body cells, resulting in 2 genetically identical daughter cells with the same amount of chromosomes.
What is meiosis?
What is meiosis?
Meiosis is the process of cell division for germ or sex cells, resulting in 4 daughter cells with half the number of chromosomes.

Study Notes
Mitosis
- Involves somatic (body) cells, essential for growth and repair.
- Consists of a single division process leading to two daughter cells.
- Daughter cells are genetically identical to the parent cell, maintaining the same chromosome number.
- Key purpose is to enable growth and replace worn-out cells.
Meiosis
- Occurs in germ (sex) cells, crucial for sexual reproduction.
- Comprises two sequential divisions, resulting in four daughter cells.
- Each daughter cell has half the chromosome count of the original parent cell, promoting genetic diversity.
- The main goal is to produce gametes (sperms and eggs) for reproduction.
Functions and Products
- Mitosis leads to growth, producing two genetically identical daughter cells from one original cell.
- Meiosis results in reproduction, generating four genetically diverse sex cells from one original germ cell.
Similarities between Mitosis and Meiosis
- Both processes involve the replication of chromosomes before division.
- They utilize chromatin and chromosomes as part of the cellular structure.
- The nuclear membrane disintegrates during the division phase in both processes.
- Chromatids, the duplicated chromosomes, separate during the division.
- Cytokinesis, the final stage of cell division, occurs in both mitosis and meiosis, ensuring separation of daughter cells.
