Unit 3: Cells B

Cell Membrane & Cell Transport

TermDefinition
active transport energy-requiring process that moves material across a cell membrane against a concentration difference
concentration the mass of solute in a given volume of solution, or mass/volume
diffusion the movement of solute across a membrane from high to low concentration
endocytosis process by which a cell takes material into the cell by infolding of the cell membrane
equilibrium when the concentration of a solute is the same throughout a solution
exocytosis process by which a cell releases large amounts of material
facilitated diffusion movement of specific molecules across cell membranes through protein channels
homeostasis process by which organisms maintain a relatively stable internal environment
hypertonic when comparing two solutions, the solution with the higher concentration of solutes
isotonic when the concentration of two solutions is the same
lipid bilayer double-layered sheet that forms the core of nearly all cell membranes
osmosis diffusion of water through a selectively permeable membrane
phagocytosis process in which extensions of cytoplasm surround and engulf large particles and take them into the cell
pinocytosis process by which a cell takes in liquid from the surrounding environment

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.
