Cell Transport Vocab

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

• osmosis

• active transport

• facilitated 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.

• diffusion

• osmosis

• facilitated diffusion

• active transport

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

• diffusion

• facilitated diffusion

• active transport

Movement of a substance across a cell membrane against its concentration gradient from lower concentration to higher concentration. Energy required.

Movement of very large molecules (into the cell) across the cell membrane through the fusion of vesicles. Energy required.

• diffusion

• endocytosis

• exocytosis

• osmosis

Movement of very large molecules (out of the cell) across the cell membrane through the fusion of vesicles. Energy required.

• diffusion

• endocytosis

• exocytosis

• osmosis

Substance dissolved in another substance.

• solute

• solvent

• isotonic

• hypotonic

The substance that dissolves another substance.

• solute

• solvent

• hypotonic

• hypertonic

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.

• solvent solution

• isotonic solution

• hypotonic solution

• 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.

• solvent solution

• isotonic solution

• hypertonic solution

• hypotonic solution
