Fluid Mosaic Model
Describes membrane structure
Tonicity
Relative solute concentration of two fluids
Plasmolysis
Loss of water in a plant cell
Crenation
Loss of water in a red blood cell
Osmosis
Diffusion of solvent across a semi-permeable membrane
Diffusion
Movement of molecules down a concentration gradient
Solvent
A substance in which solutes are dissolved
Hypertonic
One fluid has more solute than the other
Hypotonic
One fluid has less solute than the other
Isotonic
Two fluids have equal solute concentrations
the silver nitrate test for
chloride ions
distilled water is an example of
hypotonic solution
If a cell is placed in a hypotonic
it will swell
This will occur if a plant cell is placed in a hypertonic solution
plasmolysis
Lugol Iodine Test
polysaccharide
A cell is what?
selectively permeable
