Study Notes
Cell Division and Growth
- Mitosis is the process of cell division that results in two daughter cells with the same number of chromosomes as the parent cell.
- Mitosis occurs in somatic cells (non-reproductive cells) and is involved in tissue renewal and growth.
Stages of Mitosis
- During prophase, chromosomes condense and become visible, and spindle fibers form.
- During metaphase, all chromosomes line up along the plate.
- During anaphase, sister chromatids separate and move to opposite poles of the cell.
- During telophase, chromosomes uncoil and become diffuse, and the nuclear envelope reforms.
Characteristics of Mitosis
- Mitosis involves the production of two diploid daughter cells, each with the same number of chromosomes as the parent cell.
- Mitosis occurs in somatic cells, such as skin cells and muscle cells.
Meiosis
- Meiosis is the process of cell division that results in four haploid daughter cells, each with half the number of chromosomes as the parent cell.
- Meiosis occurs in reproductive cells (gametes) and is involved in the production of sex cells (sperm and egg cells).
- During meiosis, crossing over occurs in prophase I, allowing for genetic recombination and increased genetic diversity.
Characteristics of Meiosis
- Meiosis involves two rounds of cell division, resulting in four haploid daughter cells.
- Meiosis produces genetically different haploid cells, increasing genetic diversity.
Comparison of Mitosis and Meiosis
- Mitosis produces two diploid daughter cells, while meiosis produces four haploid daughter cells.
- Mitosis occurs in somatic cells, while meiosis occurs in reproductive cells.
- Mitosis does not involve crossing over, while meiosis does.
Functions of Mitosis and Meiosis
- The purpose of mitosis is to produce new cells for growth and tissue renewal.
- The purpose of meiosis is to produce genetically diverse sex cells (sperm and egg cells) for sexual reproduction.
