Diffusion Osmosis Active Transport

What indicates that osmosis has occurred in a dialysis tubing experiment?

• The size of the tubing

• A change in color of the solution

• The temperature of the solution

• A change in the water level outside the tubing

What happens to animal cells placed in distilled water?

• They lose water and shrivel

• They gain water and may burst

• They remain unchanged

• They become turgid

What is the role of water as a solvent in organisms?

• To provide energy for cellular processes

• To create pressure in cells

• To dissolve and transport substances

• To increase temperature

Which diagram best shows the end result of diffusion?

• F

• G

• H

• J

During osmosis

• water moves from high to low concentration

• large or oddly shaped molecules move across a cell membrane

• water moves when energy is used

• proteins are built
