Osmosis and Diffusion

What is the diffusion of water only across a cell or semi-permeable membrane?

• Osmosis
• Diffusion
• Active Transport
• Passive Transport

What type of cellular transport uses energy?

• Passive Transport
• Active Transport

In which case would a cell most likely shrink?

• when placed in a solution containing a high salt concentration
• when placed in a isotonic solution
• when placed in a solution containing a low pH
• when placed in a solution containing distilled water

Active transport requires energy because...

• The cell is moving something against a concentration gradient
• The cell is moving something with a concentration gradient

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of ___________.

• osmosis
• equilibrium
• diffusion
• hypertonic

In a scenario, salt is placed into a bowl of water.  What is the solvent?

• salt
• water
• saltwater

 If a cell containing 5% salt is placed into a glass of water with 20% salt, the water is _______ compared to the cell.

• hypertonic-
• hypotonic
• isotonic

The cell wall________.

• is a selectively permeable membrane
• is involved in protection and structure in plants
• is found in plants and animals

• swell (get bigger)
• shrink (get smaller)

What is diffusion?

• when molecules move 
• when molecules move from a high concentration to a low.
• no movement 
• molecules move everywhere
