Cell Membrane

Fluid Mosiac A model that refers to how the lipid bilayer acts more like a liquid than a solid. Also, has proteins.
Active Transport Energy Needed. Low to High concentration. Material moving through a protein channel.
Passive Transport No Energy needed. High to Low concentration. Includes- Osmosis, Diffusion, and Facilitated Diffusion.
Diffuion High to Low movement of molecules. No Energy.
Osmosis Diffusion of water from an area of High concentraion to an area of Low concentration.
Endocytosis Materials entering cells. ( ENdocytosis)
Exocytosis Materials exiting cells. ( EXocytosis)
Hydrophobic Substance that resists dissolving in water.
Hydrophilic Mixes with water.
Isotonic No change in cell shape. Describes a solution whose solute concentration is equal to the solute concentraion inside the cell.
Phospholipid Molecule that makes up the bilayer of biological membranes.
Hypotonic Solute concentration is lower than the solute concentraion inside the cell. ( LOW )
Hypertonic Solute concentraion is higher than the solute concentaion inside the cell. ( HIGH )
Protein Channel Passes large molecules that can't go through the membrane. It is like a channel that has a path for larger molecules to go through.
Facilitated Diffusion Passive Transport. Uses transport proteins to move substances down the concentration gradient.
Concentration Gradient Substances moving from High to Low areas.
Solution Solutes dissolved in solvents.
Solute Substance dissolved in a solution
Solvent In a solution, substance dissolves in solutes.

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.
