Cell Theory
-All living things are made up of a cell or cells
-All cells come from pre-existing cells
-All cells carry out all life processes (with the possible exception of reproduction)

Know some exceptions to cell theory

Robert Hooke (another monk/scientist) first coined the term cell while observing cork cells (which are actually just the cell walls!)

What is an organelle
Which can be seen with light microscopes? Electron microscope?

Nucleus
Cell membrane
Nuclear membrane
Vacuole
Chloroplast
Cell wall
Lysosome
Mitochondria
Flagella and cilia

How can you tell plant and animal cells apart?

Cell transport:
Osmosis and diffusion (passive transport)
Hypo/hyper/isotonic solutions (when will the cell shrink/blow up)
Osmoregulation (marine/aquatic organisms)
Turgor in plant cells

Active transport
Facilitative diffusion

Endocytosis/exocytosis
Receptor mediated endocytosis

Respiration
Where does it happen?
Aerobic vs anaerobic
    efficiency (ATP production)
    oxygen debt
fermentation-alcoholic and lactic acid
Products and raw materials
ATP and glucose

Photosynthesis
Where does it happen?-in cells and in plants
Products (including waste) and raw materials
Balance between respiration and photosynthesis

PLANTS CARRY OUT BOTH PHOTOSYNTHESIS AND RESPIRATION
