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.
