Active transport Movement of molecules from low concentration to high concentration requiring the use of energy
Diffusion Movement of molecules from an area of higher concentration to an area of lower concentration
Osmosis The movement of water across a semi-permeable membrane from a region of high water concentration to a region of low water concentration
Plasmolysis When the cell membrane shrivels away from the cell wall in a plant cell
Semi-permeable Allows some molecules to pass through but not all

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.

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.
