Water Potential and Osmosis

The movement of water molecules out of a cell and into an environment with high salt concentration is

• facilitated diffusion

• osmosis

• phagocytosis

• exocytosis

Is it safe to drink salt water?

• Yum, so salty!

• No, you could die of dehydration.

_______ regulates what enters and leaves a cell.  

• Cell Membrane
• Nucleus
• Mitochondria
• Cytoplasm

What is the definition of Equilibrium?

• the process that brings LARGE particles INTO the cell through the cell membrane
  
• The movement of molecules from an area of high concentration (where the molecules are more crowded together) to a area of low concentration (where molecules are more spread apart)
  
• the state where molecules are equally concentrated (balanced) on both sides of the cell membrane.
  
• the movement of WATER molecules across the cell membrane.
  

In the given scenario what will happen to the organism: salt is poured onto eggplant.

• Water will move out of the eggplant cells and the cells will shrink.
• Water will move out of the eggplant cells and the cells will swell.
• Water will move into the eggplant cells and the cells will swell.

In the given scenario what will happen?  An egg is placed in pure water for 48 hours.

• The egg will gain water and swell.
• Water will move in and out of the cell equally, and the cell with neither shrink nor swell.
• The egg will lose water and shrink.
