Osmotic Solutions

Different Osmotic Solutions

TermDefinition
Hypertonic Solution A solution where the concentration of particles outside the cell has MORE solute than the concentration of particles inside the cell
Hypotonic Solution A solution where the concentration of particles outside the cell has LESS solute than the concentration of particles inside the cell
Isotonic Solution A solution where the concentration of particles outside the cell has THE SAME solute than the concentration of particles inside the cell
Predict where water will move in a HYPERTONIC solution Water will move OUT OF THE CELL, and the CELL SHRINKS
Predict where water will move in a HYPOTONIC solution Water will move INTO THE CELL, and the CELL SWELLS
Predict where water will move in a ISOTONIC solution Water will move BOTH INTO AND OUT OF THE CELL, and the CELL SHAPE STAYS THE SAME
Properties of Passive Transport (1)Moving a substance into or out of the cell without using energy, (2) moving from high to low concentration
Types of Passive Transport (1) Diffusion (2) Facilitated Diffusion (3) Osmosis
Types of Active Transport (1) Endocytosis (2) Exocytosis
Properties of Active Transport (1) Substance moves into or out of a cell using energy, and (2) moving from low to high concentration
Equilibrium Particles move until they are evenly dispersed/distributed throughout
What type of cell does sodium-potassium pump occur in? Nerve Cell
What type of transport is the sodium-potassium pump an example of? Active Transport
How do gases like oxygen and carbon dioxide get into or out of the cell? Diffusion
How does glucose get into/out of the cell? Facilitated Diffusion
How does water get into/out of the cell? Osmosis
Semipermeable or Selectively Permeable Allows some things through but not all
Protein Channel A wider opening provided in the cell membrane to bring large substances into/out of the cell
Carrier Protein A protein in the cell membrane that changes shape to bring substances into/out of the cell
Are protein channels used for active or passive transport? Passive Transport, like in facilitated diffusion
Are carrier proteins used for active or passive transport? Active Transport, like the sodium-potassium pump

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.
