the relative concentration of solute (and also solvent) outside the cell compared to inside the cell
|
tonicity
|
there are 3 types
|
|
the same concentration of solute (and therefore water) as the cell.
|
isotonic solution
|
in this solution there no net movement of water
|
|
has a higher solute (therefore, lower water) concentration than the cell
|
hypertonic solution
|
in this solution water moves out of the cell into the solution
|
|
has a lower soluter concentration (therefore higher water) than the cell
|
hypotonic solution
|
in this solution water moves from the solution into the cell
|
|
the pressure exerted when a plant cell is in a hypotonic solution and the large central vaculoe gains water
|
turgor pressure
|
|
|
when plant cells are in a hypertonic solution, the central vacuole loses water, and the cytoplasm, including the chloroplasts, pulls away from the cell wall
|
plasmolysis
|
|
|
small membranous bodies, each with a specific function and structure
|
organelles
|
only eukaryotic cells have these
|
|
material bounded by a plasma membrane and cell wall
|
cytoplasm
|
|
|
polar molecules
|
molecules with charged groups or atoms
|
|
|
nonpolar molecules
|
molecules with no charged groups or atoms
|
|
|
causes fat to disperse in water and has molecules with both polar and non polar ends
|
emulsifiers
|
|
|
emulsifiers found in bile produced by the liver
|
bile salts
|
used in the digestive tract
|
|
smallest unit of life
|
cell
