TRANSCRIPT

  • 1. Cell Reproduction
    • Prokaryotes Bacteria
  • Eukaryotes Plants & animals

2. Eukaryotes

  • Contain a nucleus & membrane bound organelles
  • Asexually reproduce (divide) cells by mitosis for the purpose of
    • repair damaged cells
    • growth of organism
    • development of organism

3. Cell Cycle

  • Stages in growth & division
  • Interphase
    • G1Phase
    • S Phase
    • G2 Phase
  • M Phase
  • Cytokinesis

4. Interphase Resting Stage

  • Cells carrying on normal activities
  • Chromosomes arent visible
  • Cell metabolism is occurring
  • Occurs before mitosis

5. Interphase 6. Interphase - G1 Phase

  • First growth stage
  • Cell increases in size
  • Cell prepares to copy its DNA

7. Interphase - Synthesis Phase

  • Copying of all of DNAs instructions
  • Chromosomes duplicated

8. Interphase - G2 Phase

  • Time between DNA synthesis & mitosis
  • Cell continues growing
  • Needed proteins produced

9. M Phase (mitosis)

  • Cell growth & protein production stop
  • Cells energy used to make 2 daughter cells
  • Called mitosis or karyokinesis (nuclear division)

10. Life Cycle of a Cell Mitosis is a cycle with no beginning or end . 11. Cells Undergoing Various Stages of Mitosis 12. Stages of Mitosis

  • Prophase
  • Metaphase
  • Anaphase
  • Telophase
  • Remember: PMAT

13. Cytokinesis

  • Means division of cytoplasm and all organelles within
  • Occurs after chromosomes separate
  • Forms two, identical daughter cells

14. Cytokinesis Cell Plate Forming in Plant Cells 15. Cytokinesis Cleavage furrow in animal cell Cell plate in animal cell
