Cell Transport

How molecules move in cells

TermDefinition
semipermeable a property of a cell that allows some materials to cross and not others
Diffusion Movement of molecules from an area of high concentration to an area of to low concentration
Osmosis Diffusion of water across a cell membrane
Dynamic Equilibrium Molecules are evenly spread throughout a space; Result of diffusion where there is continuous movement of particles, but no overall change in concentration.
Cell Membrane Controls what comes in and out of the cell.
Facilitated Diffusion When carrier proteins moves molecules across the membrane. Does not require energy. Example - glucose and amino acids
Phospholipid Molecules that make up the cell membrane. It has a "head" and two "tails".
Carrier Protein Proteins that are in the cell membrane that help move substances in and out of the cell.
Passive Transport When molecules move with the concentration from high to low concentration, with no energy required.
Types of Passive Transport -Diffusion -Osmosis -Facilitated Diffusion
Types of Active Transport - Endocytosis - Exocytosis
Concentration Gradient a place where the density of a chemical substance, increases or decreases.
Active transport the movement of molecules from lower to higher concentration while using energy
Exocytosis (release/secretion of molecules).
Endocytosis (the intake/uptake of molecules).
Hydrophilic The HEAD of a phospholipid molecule. They love water!
Hydrophobic The TAIL of a phospholipid molecule. They hate water!
Hypertonic Solution More solute in the solution outside the cell, so the lose will lose water and shrivel
Hypotonic Solution More solute in the cell than the surrounding solution, so water will rush in and make the cell swell
Isotonic Solution Equal amount of water and solute in and out of the cell, so water will continue to flow in and out of the cell
Solute . A substance that dissolves in a solution. (like salt)
Solvent In a solution, the substances in which the solute dissolves. (like water).
Phagocytosis a type of endocytosis, where SOLID particles are brought into the cell.
Pinocytosis a type of endocytosis, where LIQUID particles are brought into the cell.
Active Transport The movement of a substance across a cell membrane using energy. Low to high concentration.

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.
