Have a working knowledge of the following:
cell membrane structure and functions
cause of membrane fluidity
function of cell membrane proteins
molecules that easily pass through the cell membrane
function of aquaporins
tonicity
osmosis
water balance of cells: hypotonic, hypertonic, isotonic, flaccid, turgid, plasmolyzed;
lysis
solute concentrations at equilibrium
facilitated diffusion
active transport—what it is and when it is used
electrogenic pump
 proton pump
 Na+/ K+ pump
membrane potential
electrochemical gradient
glucose transport into the cell
sucrose loading by plant
water potential: what it is and how to work the problems and from that figure out the
direction of water flow
