  1. INTRO TO CELL DIVISION

  2. Organisms can reproduce… - simple cell division • _____________________ - cell duplicates genetic material - 2 new genetically identical cells • ______________________ - two parents - genetic material from each parent combine - genetically different offspring

  3. Roles of cell reproduction • Replacement of _____ or ______ cells • _____________ • Production of ______________

  4. THE CELL CYCLE * Events from “birth” of eukaryotic cell to when it reproduces * How ________ a cell divides depends on the type of cell it is. _____________: muscle cells, nerve cells (neurons), and liver cells ______________: cells that line stomach and mouth, skin cells

  5. Before cell division…INTERPHASE • Cell carries out __________________and performs functions • Up to ___________of cell the cell cycle is spent in interphase

  6. - cell grows and carries out cellular functions ______________ phase - protein synthesis - cell  s the # of organelles ______________ phase - DNA duplicates ______________ phase - continued growth and metabolism - protein synthesis

  7. CHECKPOINT #1 (after G1) 2) Need for new cells? 3) DNA undamaged? 1) Enough growth?

  8. CHECKPOINT #2 (after G2) 1) DNA replicated? 2) Enough growth?

  9. M (mitotic) PHASE • Cell actively _______________ • ________________ and ________________

  10. Terms • Chromatin – • Chromosomes – • Diploid cells – • Haploid cells – • Homologous Chromosomes – • Genes –

  11. PROPHASE

  12. METAPHASE

  13. ANAPHASE

  14. TELOPHASE

  15. Cells in a cancerous tumor ____________at an abnormally fast rate and become irregular in appearance. • When individual cells ___________(travel from the original tumor), the cancer can spread.
