Science Quiz #4 Term

Cell Transport and Elimination Part II

The rate of diffusion depends on... Temperature, size of the molecules, type of molecules diffusing and the concentration of the molecules is the same on both sides of the membrane
Osmosis... the diffusion of water across a semi-permeable membrane
Water moves from areas of low solute... to areas of high solute
Water molecules will cross membranes until the concentrations of water... and solutes is equal on both sides of the membrane called equilibrium
At equilibrium, molecules continue to move across membranes... evenly so there is no net movement
Hypertonic Solution solute concentration... outside the cell is higher
Hypotonic Solution solute concentration greater... inside the cell
Isotonic Solution concentration of solutes... same inside and outside the cell
The cell of animals on land are... usually in isotonic environment
Freshwater organisms live in hypotonic environments so water... constantly moves into their cells
Unicellular freshwater organisms... use energy to pump out excess water by contractile vacuoles
Plant cell walls prevent plant cells from... bursting in hypotonic environments
Some marine organisms can... pump out excess salt

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.
