Osmosis and Diffusion

Osmosis is the movement of what across a membrane?

• Glucose

• Sodium

• Water

• Lipids

Isotonic solutions...

• ...have the same tonicity as inside the cell.

• ...have a higher tonicity than inside the cell.

• ...have a lower tonicity than inside the cell.

Hypotonic solutions...

• ...have the same tonicity as inside the cell.

• ...have a higher tonicity than inside the cell.

• ...have a lower tonicity than inside the cell.

Hypertonic solutions...

• ...have the same tonicity as inside the cell.

• ...have a higher tonicity than inside the cell.

• ...have a lower tonicity than inside the cell.

Diffusion mean to...

• ...come together.

• ...make groups.

• ...move away from.

• ...spread out.

Osmosis is an example of...

• ...passive transport.

• ...active transport.

If a solution is hypertonic to the inside of a cell, water will...

• ...diffuse back and forth to and from the cell.

• ...diffuse into the cell.

• ...diffuse out of the cell.
