Stack #704832

QuestionAnswer
osomosis water passes through a selectively permable membrane
the cell wall is found in what bacteria, plant, and protista
cell walls form what protection and structure
how do substances move in cells within and across membranes
active and passive transport the process that substances move within and across cell membranes
concentratino graident the number of molecules or ions in one region is different than the number in another region.
diffusion movement from an ara of high concetration to an area of low concentration
kinetic energy of the molecules is... is necceessary; no additional energy is required
diffusion will occur until.. there is equal amounts of solute spread throughout the system: equilibrium
steepness if the concentration gradient - steeper gradient =.... faster diffusion
molecule size - smaller molecules =... faster diffusion
temperature - higer temp. = ... faster diffuision
water moves to equalize concentration inside and outside of the cell
a protien channel allows specific molecules to move across the cell membrane
a passive transport does not require what energy

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.
