selectively permeable
allows only some molecules to pass through. Small or uncharged (non-polar)
diffusion
the movement of small molecules through through the membrane.
osmosis
the diffusion of water molecules from [H]->[L] through a channel protien calles aquaporin
passive transport
requires no energy, goes from [H]->[L] across the concentration gradient
active transport
requires energy and a channel protein to allow molecules to pass through the membrane [L]->[H]
vesicles
transport that contain large molecules
endocytosis
brings contents into the cell via vesicles (also called phagocytosis or pinocytosis)
exocytosis
removing contents from the cell via vesicles
ocean water (salt)
solute
ocean water (water)
solvent
crenate
animal when placed into a hypertonic solution, water will leave the cell to try and reach equilibrium
plasmolyze
plant when placed into a hypertonic solution, water will leave the cell to try and reach equilibrium
lyse
animal when placed into a hypotonic solution, the water will diffuse into the cell making it gain weight, when it lyses it will pop
increased turgor pressure
plant when placed into a hypotonic solution will diffuse into the cell making it gain weight will not pop because of the cell wall, the cell membrane will put pressure from inside
isotonic
when the solute and solution are equal, doesn't gain ore lose weight
hypertonic
when there is more solute than solvent, the cell will lose weight
hypotonic
when there is more solvent than solute, the cell will gain weight
