  4. what happens during the S phase
    DNA replication
  5. what happens during g2?
    • organelle production
    • centriole replication compmletes
  6. what are the 4 phases of mitosis?
    • prophase
    • metaphase
    • anaphase
    • telephase
  7. what happens during prophase?
    • nuclear membrane and nucleoli break up
    • centrioles seperate
    • spindle formation begins
  8. what happens during anaphase?
    • centrometers seperate
    • pairs are pulled to opposite poles
  9. what happens during telophase?
    everything reassembles
  10. what does cytokinesis occur?
    • overlaps anaphase and telophase
    • division of t he cytoplasm and organelles
  11. when can cell death happen?
    any point of division
  12. two ways of cell death?
    • necrosis
    • apoptosis
  13. passive transport systems?
    • diffusion
    • osmosis
    • facilitated diffusion
    • filtration
  14. 3 types of tonicity
    • isotonic
    • hypotonic
    • hypertonic

    • active transport
    • bulk transport
  16. different types of bulk transports
    • endocytosis
    • exocytosis
    • transcytosis
  17. phagocytosis?
    • cell eating
    • outside cell >> into cell
    • moving particles
  18. pinocytosis?
    moving fluids from outside to inside
  19. receptor-mediated endocytosis
    certain particles bind to the membrane
  20. what does cholesterol do?
    effects membrane fluidity
