Cell Transport Vocabulary

TermDefinition
Passive transport The movement of substances across a cell membrane without the use of energy by the cell
Osmosis The diffusion of water
Isotonic A solution whose solute concentration is equal to the solute concentration inside the cell
Facilitated diffusion The transport of substances through a cell membrane along a concentration gradient with the aid of carrier proteins
Endocytosis The process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell
Phagocytosis The process by which a cell engulfs large particles or whole cells, either as a defense mechanism or as a means to obtain food
Sodium-Potassium Pump A carrier protein that used ATP to actively transport sodium ions out of a cell and potassium ions into the cell
Diffusion The movement of particles from regions of higher density to regions of lower density
Concentration gradiant A difference in the concentration of a s substance across a distance
Exocytosis The process by which a substance is released from the cell through a vesicle that transports the substance to the cell surface and expels it.
Hypotonic Describes a solution whose solute concentration is lower than the solute concentration inside a cell
Hypertonic Describes a solution whose solute concentration is higher than the solute concentration inside a cells
Contractile Vacuole An organelle that accumulates water and then releases it periodically to maintain osmotic pressure
Plasmolysis The contraction or shrinking of the cell membrane
Cytolysis The bursting of a cell
Carrier protein A protein that transports substances across a cell membrane
Ion channel A complex of protein molecules in a cell membrane that form a pore through which ions can pass
Active transport The movement of chemical substances across the cell membrane against a concentration gradient; requires cells to use energy
Pinocytosis A method of active transport across the cell membrane in which the cell takes in extracellular fluids

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
