Diffusion - ANS_Movement of particles or molecules from an area of high concentration to an area of low concentration
Osmosis - ANS_Diffusion of water across a selectively permeable membrane
Selectively pemeable membrane - ANS_A membrane that allows certain materials to pass through, but not others
Tonicity - ANS_A description of the relative solute concentration in a solution as compared to another solution.
Equilibrium - ANS_The condition that exists in system when there is a relatively equal distribution of a particular molecule
Hypertonic - ANS_A solution that has a higher concentration of solutes than another.
Hypotonic - ANS_A solution that has a lower concentration of solutes than another.
Isotonic - ANS_Two solutions that have an equal concentration of solutes.
Solute - ANS_substance that is dissolved in a solution
Solvent - ANS_the liquid that contains the dissolved solute in a solution.
Cell Membrane - ANS_regulates and controls what enters or leaves the cell
Facilitated Diffusion - ANS_this form of diffusion is regulated by protein channels in the membrane and requires no energy input from the cell
Active Transport - ANS_movement of molecules or ion into or out of the cell against its concentration gradient (from low to high) and requires an input of energy.
Endocytosis - ANS_movement of substances into the cell by creating a new vacuole at the cell membrane. requires energy.
Exocytosis - ANS_movement of substances out of a cell by merging a vacuole with the cell membrane. requires energy.

Cell Membrane - ANS_Composed of a phospholipid bilayer
Phospholipid - ANS_molecule that makes up cell membranes. It has a hydrophilic "head" and two hydrophobic "tails".
Hydrophilic - ANS_water loving. substances that easily mix with water.
Hydrophobic - ANS_water hating. substances that will not mix with water.
