QuestionAnswer
membrane pumps protein molecules embedded in the cell membrane that transport molecules across the cell membrane against the concentration gradient.
Endocytosis the process in which cells bring the process in which cells bring large molecules inside by surrounding them with the cell membrane and forming vesicles.
Exocytosis the process in which cells package materials into vesicles using the Golgi apparatus, and expel the vesicles from the cell.
diffusion involves the movement of material across the cell membrane from an area of high concentration to an area of low concentration.
facilitated diffusion a type of diffusion that uses special transport proteins to transfer larger molecules across cell membranes.
osmosis a type of diffusion that specifically involves the movement of water.
filtration involves the movement of water and solute molecules across the cell membrane due to hydrostatic pressure.
osmosis the movement of water molecules across the cell membrane. Water moves down a concentration gradient from areas of high water concentration to areas of low water concentration.

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.
