EXAM
osmotic pressure - ANSWERS-a measure of the tendency of a solution
to take up water when separated from pure water by a selectively
permeable membrane
tonicity - ANSWERS-ability of a solution to cause a cell within it to
gain or lose water
isotonic - ANSWERS-having the same solute concentration as another
solution
hypertonic - ANSWERS-in comparing two solutions, the one with a
greater concentration
hypotonic - ANSWERS-in comparing two solutions, the one with a
lower concentration
facilitated diffusion - ANSWERS-passive transport mediated by channel
proteins and carrier proteins
channel proteins - ANSWERS-possess a hydrophilic channel through
which atomic ions and some small molecules can pass through

EXAM
carrier proteins - ANSWERS-undergo a shape change which takes small
ions or molecules across
active transport - ANSWERS-movement of a substance across a
membrane, through a transport protein, against a chemical or
electrochemical gradient (uses ATP)
exocytosis - ANSWERS-vesicular removal of molecules to the
extracellular fluid
endocytosis - ANSWERS-vesicular uptake of molecules from the
extracellular fluid
phagocytosis - ANSWERS-uptake of large, bulky material
pinocytosis - ANSWERS-non-specific uptake of fluid from extracellular
fluid

EXAM
receptor-mediated endocytosis - ANSWERS-uptake of specific
molecules from extracellular fluid
cell theory - ANSWERS-all living things are composed of cells and the
products of cells
the cell is the functional unit of life
microscopes - ANSWERS-TEM (reveals internal details)
SEM (reveals surface details)
light (magnifys surface details)
magnification - ANSWERS-ratio of an object's image to it's real size
increase in the apparent size of an object
resolving power - ANSWERS-minimum distance two points can be
separated and still be distinguished as two separate points
prokaryotic cells - ANSWERS-small and 'simple'
bacteria and archaea
