Cell Transport

Wow

QuestionAnswer
Phospholipid Has a hydrophilic head on the top (Glycerol) and a hydrophobic tail on the bottom (Fatty Acids).
Phospholipid Bilayer Two layers of phospholipids in a cell membrane.
Hydrophobic Region Tails of a phospholipid that contain fatty acids. (Water Fearing)
Hydrophilic Region Heads of a phospholipid that contain glycerol. (Water Loving)
Glycerol The heads of the phospholipid.
Fatty Acids The tails of the phospholipid.
Receptor Protein Receives messages from molecules.
Transport Protein Moves small not ions molecules for facilitated diffusion and moves large ions molecules for active transport (the example).
Semi-permeable Only allows small molecules to pass freely.
Cholesterol Controls the flexibility of the phospholipid.
Passive Transport Don’t need energy and move from high to low concentration. Reaches equilibrium, are small non-charged ions.
Concentration Gradient Different amount of molecules on both sides.
Dynamic Equilibrium To have the same molecules on both sides.
Diffusion Movement of gas in and out of the cell.
Osmosis Movement of water in and out of the cell.
Facilitated Diffusion Is a transport protein. Movement of glucose. Need amino acids.
Active Transport (the type) Need energy, move from low to high concentration. Does not reach equilibrium, are large charged ions.
Isotonic Solution Equal amount of solute in solution. Makes the cell membrane the same. Tap Water (Salt, Water) (4, 96) (4, 96)
Hypertonic Solution Higher amount of solute in solution. Makes the cell membrane smaller. Salt Water (Salt, Water) (4, 96) (10, 90)
Hypotonic Solution Lower amount of solute in solution. Makes the cell membrane larger. Distilled Water (Salt, Water) (4, 96) (0, 100)
Active Transport (the example) Large charged ion molecules that use transport proteins which are starch and protein.
Endocytosis Membrane that takes in a lot of grouped materials.
Exocytosis Vesicles are connected with the membrane, and move out a lot of materials grouped in the cell.
Phagocytosis Is food and bacteria that goes into the cell.
Pinocytosis Liquids that enter the cell.
High to Low Concentration More Outside or More Of The Same Molecule
Low to High Concentration Less Outside or Less Of The Same Molecule

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.
