amphi- dual (amphipathic molecule: a molecule that has both a hydrophobic and a hydrophilic region)
aqua- water; -pori a small opening (aquaporin: a transport protein in the plasma membrane of a plant or animal cell that specifically facilitates the diffusion of water across the membrane)
co- together; trans- across (cotransport: the coupling of the “downhill” diffusion of one substance to the “uphill” transport of another against its own concentration gradient)
electro- electricity; -genic producing (electrogenic pump: an ion transport protein generating voltage across a membrane)
endo- inner; cyto- cell (endocytosis: the movement of materials into a cell; cell-eating)
exo- outer (exocytosis: the movement of materials out of a cell)
hyper- exceeding; -tonus tension (hypertonic: a solution with a higher concentration of solutes)
hypo- lower (hypotonic: a solution with a lower concentration of solutes)
iso- same (isotonic: solutions with equal concentrations of solutes)
phago- eat (phagocytosis: cell-eating)
pino- drink (pinocytosis: cell-drinking)
plasm- molded; -lyso loosen (plasmolysis: a phenomenon in walled cells in which the cytoplasm shrivels and the plasma membrane pulls away from the cell wall when the cell loses water to a hypertonic environment)
