Term	Definition
Active Transport	Movement of a substance across a cell membrane against its concentration gradient from lower concentration to higher concentration. Energy required.
Exocytosis	Movement of very large molecules (out of the cell) across the cell membrane through the fusion of vesicles. Energy required.
Solvent	The substance that dissolves another substance.
Hypertonic solution	Concentration (amount) of solutes OUTSIDE of the cell membrane is GREATER than inside cell; this promotes a greater flow of water outside the cell thus leading to cell shrinking.
Homeostasis	process by which biological systems, including the cell, tend to maintain stability
Diffusion	Movement of both solvent and solute particles from high concentration to low concentration in order to equalize the concentration of the solution. No energy required.
Hypotonic solution	Concentration (amount) of solutes OUTSIDE of the cell membrane is LESS than inside the cell; this promotes a greater flow of water inside the cell thus leading to cell bursting.
Solute	Substance dissolved in another substance.
Endocytosis	Movement of very large molecules (into the cell) across the cell membrane through the fusion of vesicles. Energy required.
Facilitated Diffusion	Movement of specific molecules down a concentration gradient (from high concentration to low concentration) passing through the membrane via a specific carrier protein. No energy required.
Osmosis	Movement of a solvent (usually water) from a low solute concentration to a high solute concentration in order to equalize the concentration of the two solutions. No energy required.
Isotonic solution	Concentration (amount) of solutes is equal on both sides of the cell membrane; this allows the flow of water through the cell membrane to be equal.
