CELL DIVISION
An Overview of Mitosis and Meiosis
Prepared BY: Maria Johanna Baguio Testa
WHAT IS CELL DIVISION?
- Cell division is the process by which a parent cell divides into two or more daughter cells.
- It is essential for growth, development, and repair in multicellular organisms.
Two main types: Mitosis and Meiosis
IMPORTANCE OF CELL DIVISION
- - Growth of organisms
- - Repair of damaged tissues
- - Asexual reproduction
- - Formation of gametes (sex cells)
MITOSIS OVERVIEW
Mitosis is the process by which a single cell divides to produce two identical daughter cells.
- It is used for growth and repair.
Stages of Mitosis:
- - Prophase
- - Metaphase
- - Anaphase
- - Telophase
- - Cytokinesis
MEIOSIS OVERVIEW
- Meiosis is the process that produces gametes (sperm and egg cells).
- It reduces the chromosome number by half.
- Two rounds of division: Meiosis I and Meiosis II
- Results in four non-identical daughter cells
COMPARISON: MITOSIS VS MEIOSIS
Mitosis:
- - One division
- - Two identical cells
- - Used for growth and repair
Meiosis:
- - Two divisions
- - Four non-identical cells
- - Produces gametes
SUMMARY
- Cell division is vital for life.
- Mitosis results in identical cells for growth and repair.
- Meiosis results in genetically unique cells for reproduction.
- Understanding cell division helps explain biological inheritance and development.
