Cell Transport

QuestionAnswer
semipermeable only some particles enter and exit the cell while others are not able to move through the membrane
cell membrane maintains homeostasis and regulates what comes in and out of the cell
diffusion movement of particles from a high concentration to a low concentration
osmosis the diffusion of water from a high to low concentration water concentration toward the higher concentration of solute
facilitated diffusion the use of a carrier protein to move substances from a high to low concentration. No energy required
passive transport a type of movement the does not require energy, moves substances down the gradient from a high to low concentration
active transport a type of movement that requires energy, moves substances against the gradient from low to high
isotonic equal(same) movement of water in and out of the cell
hypertonic more solute outside the cell and less water so water leaves the cell and the cell shrinks
hypotonic less solute outside the cell and more water so water enters the cell and the cell swells
phagocytosis large particles(food or bacteria) are surrounded and engulfed by the cell membrane
pinocytosis liquid is brought in by a vesicle
exocytosis cell pushes large particles and materials outside the cell
active transport examples endocytosis, exocytosis, protein pump
passive transport examples diffusion, osmosis, facilitated diffusion
endocytosis cell engulfs and pulls in large particles and materials into the cell
protein pump transport protein that uses energy to move molecules from low to high concentration
Water LOVES Solute
Cell transport type that doesn't use energy passive transport
Cell transport type that DOES use energy active transport
If water moves into the cell the surrounding solution is ______ Hypotonic
If water moves out of the cell, the surrounding solution is ______ Hypertonic

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.
