  1. Simple diffusion
    • NO ATP
    • NO carrier molecule
    • [high] to [low] concentration gradient
  2. Facilitated diffusion
    • NO ATP
    • YES carrier molecule
    • [high] to [low] concentration gradient
  3. Active Transport
    • YES ATP requirement
    • YES carrier molecule
    • [low] to [high] concentration gradient
  4. Osmosis & cells
    • Isotomic: same amount of water in the cell and the beaker
    • Hypertomic: crenation; shrinking of the cell
    • Hypotonic: lysis
  5. Membrane projections
    • Cilia:
    • Flagella: only sperm cell; only purpose to move in it's environment
    • Microvilli: increase surface area to absorb nutrients
  6. Ribosomes
    protein synthesis
  7. Mitochandria
    small DNA found in mitochandria; it is the power house of the cell =
  8. Rough ER [endoplasmic recticulum)
    with ribosomes; protein synthesis
  9. Smooth ER [endoplasmic recticulum]
    without ribosomes; produces lipids
  10. Golgi apparatus
    not attached to nuclei envelope
  11. Lysosomes
    digestive enzymes
  12. Centrioles
    separation of chromosomes and mitosis
  13. Mitosis
    • Prophase
    • Metaphase
    • Anaphase
    • Telophase
    • Cytokinesis
  14. Prophase
    necleu envelop dissolves; chromosomes dispersed
  15. Metaphase
    lined up in the middle (center) for metaphase
  16. Anaphase
    chromosomes pull apart from each other
  17. Telophase
    recreate nuclei envelope
  18. Cytokinesis
    cyto=cut; form two (2) daughter cells
