Diffusion & Osmosis

GTCC BIO 168

TermDefinition
Osmosis Movement of water only
Passive Transport The movement of water molecules traveling across the membrane Does not require energy
High Water concentration a solution has a lot of water molecules and very few dissolved parts, like salt or sugar
Low Water Concentration Greater Solute Concentration
Solute salt and sugar that dissolves
Solvent usually a liquid (Water)
Hypertonic (high) High solute concentration
Hypotonic (low) Low solute concentration (Less)
Isotonic = ISO means same equal tension
Valence shell outside of an atom
Concentration Gradient spread out or move from an area of high (crowded) to low (less crowded)
Diffusion movement of solvent (salt/sugar) spread out until equally distributed. Down the concentration gradient
Water will follow Salt, sugar, and protein
Hemolysis break the red blood cells (explode)
Crenation Shrinks/Dehydrates the cell
Semi-permeable membrane some things, not all, passes through. Based on the size, shape, charge, and if lipid.
Solution Solvent + Solute
Tonicity Concentration of stuff

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.
