concentration gradient a difference in the concentration of a substance across a distance
equilibrium a state that exists wen the concentration of a substance is the same throughout a space
osmosis the diffusion of water or another solvent from a more dilute solution to a more concentrated solution through a membrane that is permeable to the solvent
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 cell
isotonic describes a solution whose solute concentration is equal to the solute concentration inside a cell
contractile vacuole in protists, an organelle that accumulates water and then releases it periodically to maintain osmotic pressure
turgor pressure the pressure that is exerted on the inside of cell walls and that is caused by the movement of water into the cells
plasmolysis the contraction or shrinking of the cell membrane of a plant cell in a hypertonic solution in response to the loss of water by osmosis
cytolysis the bursting of a cell
facilitated diffusion the transport of substances through the cell membrane along a concentration gradient with the aid of carrier proteins

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.
