Cell Division

• What is the function of mitosis?


  Repair, growth and replacement
• What is the function of meiosis?

  Production of gametes (sex cells like sperm)
• Meiosis= 2 cell division to produce 4 haploid (different) cells in the sex organs
• Mitosis= 1 Cell division that produces 2 diploid (identical) cells all over the body

  
• Meiosis= 2 cell division to produce 4 haploid (different) cells in the sex organs

  
• Cells need to divide as we need them for:

  • Growth
  • Repair damaged tissue
  • Replace worn out cells
  • Asexual Reproduction
• Cell Cycle:

  1. Organelles and DNA doubles
  2. Mitosis divides DNA
  3. Cell membrane divides
