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., 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., 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., Active Transport - Movement of a substance across a cell membrane against its concentration gradient from lower concentration to higher concentration. Energy required., Endocytosis - Movement of very large molecules (into the cell) across the cell membrane through the fusion of vesicles. Energy required., Exocytosis - Movement of very large molecules (out of the cell) across the cell membrane through the fusion of vesicles. Energy required., Solute - Substance dissolved in another substance., Solvent - The substance that dissolves another substance., 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., 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., 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., Homeostasis - process by which biological systems, including the cell, tend to maintain stability,
