Cell Transport

Particles in a solution tend to move from an area of HIGH concentration to an area of LOW concentration. Diffusion
The diffusion of water. Osmosis
When the concentration of solutes is the same on each side of the cell, the cell has reached a state of ____________________. Equilibrium
Barriers that allow some things to pass through, but not all things. Semi-permeable OR selectively permeable membranes
A type of diffusion that uses transport proteins in the cell membrane to help move large molecules into/out of cells. Facilitated diffusion
TRUE or FALSE: Passive transport (diffusion, osmosis, facilitated diffusion), requires energy in order to occur. FALSE
TRUE or FALSE: Active transport (endocytosis, exocytosis), requires energy in order to occur. TRUE
The process of moving molecules INTO the cell. Endocytosis
The process of releasing molecules OUT of the cell. Exocytosis
A type of endocytosis that involves extensions of the cytoplasm reaching out to surround a molecule and bring it into the cell. Phagocytosis
A type of endocytosis that involves forming pockets in the cell membrane to suck liquids and other particles into the cell. Pinocytosis
Solution in which the solute concentrations are the same inside the cell as they are outside of the cell. Isotonic
Solution in which water leaves the cell because the concentration of solutes outside of the cell is greater than it is inside of the cell. Hypertonic
Solution in which water enters the cell because the concentration of solutes outside of the cell is less than it is inside of the cell. Hypotonic
A type of cell transport that requires energy to move molecules against the concentration gradient (from low to high concentration). Active Transport

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.
