Cell Transport Vocab

Front

Movement of solvent from low to high solute concentration to equalize solutions. No energy required.

Back

osmosis

Front

Movement of solvent and solute from high to low concentration to equalize solution. No energy required.

Back

diffusion

Front

Movement of molecules down a concentration gradient through a carrier protein without energy.

Back

facilitated diffusion

Front

Movement of a substance across a cell membrane against its concentration gradient, requiring energy.

Back

active transport

Front

Movement of large molecules into the cell via vesicle fusion. Requires energy.

Back

endocytosis

Front

Movement of large molecules out of the cell via vesicle fusion. Requires energy.

Back

exocytosis

Front

Substance dissolved in another substance.

Back

solute

Front

Substance that dissolves another.

Back

solvent

Front

Concentration of solutes is equal on both sides of the cell membrane, allowing equal water flow.

Back

isotonic solution

Front

Concentration of solutes outside the cell is greater than inside, causing water to flow out and the cell to shrink.

Back

hypertonic solution
