Diffusion - (ANSWER)Movement of molecules from an area of higher
concentration to an area of lower concentration.
concentration gradient - (ANSWER)when molecules are unevenly distributed
resulting in an area of higher and lower concentration
what is the correlation between molecular mass and rate of diffusion -
(ANSWER)the larger and heavier the molecule the slower it will diffuse
osmosis - (ANSWER)Diffusion of water through a selectively permeable
membrane
selectivly permeable membrane - (ANSWER)membrane that only allows certain
things to come in while keeping other things out
hypertonic - (ANSWER)the concentration of solutes is greater outside the cell
than inside it
hypotonic - (ANSWER)the concentration of solutes is greater inside the cell than
outside of it
, isotonic - (ANSWER)the concentration of solutes is the same inside and outside
the cell
apical surface of epithelial tissue - (ANSWER)layer of cells closest to the lumen
basal surface - (ANSWER)The bottom layer of epithelial tissue that attaches to
the basement membrane
basement membrane - (ANSWER)Cells at the base of an epithelial layer are
attached to this.
simple epithelium - (ANSWER)single layer of cells
stratified epithelium - (ANSWER)multiple layers of cells
goblet cells - (ANSWER)cells that secrete mucus
cilia - (ANSWER)The hairlike projections on the outside of cells that move in a
wavelike manner
