Osmosis and Cell Behavior Flashcard

Front

What indicates a positive result when testing for glucose using a glucose indicator strip?

Back

The solution is golden brown.

Front

What happens to cells placed in a hypertonic solution, such as saltwater?

Back

Cells will shrink.

Front

What does selective permeability allow the cell to do?

Back

Control what substances can enter or leave the cell.

Front

What is the significance of dialysis tubing in diffusion/osmosis experiments?

Back

It acts as an artificial cell membrane.

Front

What is an example of active transport?

Back

Sodium-potassium pump moving ions against their concentration gradient.

Front

Define osmosis.

Back

The movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to another solution.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to another solution.

Front

What is isotonic solution?

Back

A solution with the same concentration of solutes as another solution.

Front

Explain the process of diffusion.

Back

The movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached.
