A difference in concentration from one area to another
Concentration Gradient
An organisms that can only handle small fluctuations in salinity
Stenohaline
Flexible protein coat on the outside of the cell
Pellicle
When the solutes in the environment are higher than the solutes inside the cell
Hypertonic
Hard mineral or proteinaceous coat on the outside of the cell
Test
A measure of the tendency of water to move from one area to another
Water potential
An organism that can maintain different water levels from the environment
Osmoregulator
The concentration of solutes inside the cell is the same as the solutes in the environment
Isotonic environment
The influence of physical forces on the tendency of water to move from one area to another
Pressure Potential
An organism that has water levels that always matches its environment
Osmoconformer
The influence of relative solute concentrations on the tendency of water to move from one area
to another
Solute Potential
The diffusion of water across a membrane
Osmosis
The solutes in the environment are lower than the solutes in the cell
Hypotonic environment
Organisms that can handle large fluctuations in salinity
Euryhaline
Molecule made up of a large chain of glucose
Cellulose
When a molecule(or ion) goes from high concentration to low concentration
Diffusion
A structure surrounding a cell mainly made up of cellulose or chitin.
Cell Wall
Found in plants, bacteria, seaweeds, and chitin
