Cell division by mitosis

• Mitosis


  The process of cell division that produces two genetically identical daughter cells
• Cell cycle involving mitosis

  • DNA replication
  • Chromosome separation
  • Cytoplasm and cell membrane division
• Body cells contain 23 pairs of chromosomes
• Gametes have unpaired chromosomes
• Chromosomes


  Carry a large number of genes that determine many of our features
• Animals and plants contain a very large number of cells
• Cells can divide by either mitosis or meiosis
• Cell cycle including mitosis

  1. DNA replication

  2. Chromosome separation

  3. Cytoplasm and cell membrane division
• Mitosis copies one cell into two identical cells
• Functions of mitosis


  • Growth and development of multicellular organisms
  • Repair of organisms
  • Asexual reproduction
