Cell Transport

Which of the following molecules crosses through a semipermeable membrane during the process of osmosis?

• Glucose

• Sodium

• Proteins

• Water

An animal cell has a 2% percent salt concentration. It is placed into a solution with a 0.05% salt concentration.

• Water will move out of the animal cell, causing it to shrivel.

• Water will move out of the animal cell, causing it to swell and burst.

• Water will move into the animal cell, causing it to shrivel.

• Water will move into the animal cell, causing it to swell and burst.

The image below shows molecules of carbon dioxide gas in a box. The box is divided into two sections of equal volume by a membrane which is permeable to carbon dioxide. Which of the following scenarios is most likely to occur?

• There will be a net movement of carbon dioxide molecules from right to left.

• There will be no net movement of carbon dioxide molecules.

• There will be a net movement of carbon dioxide molecules from left to right.

• There will be a net movement of the carbon dioxide molecules from the top of the box to bottom of the box.

In which direction do particles in a solution move during passive diffusion?

• From lower to higher areas of concentration

• From right to left

• From higher to lower areas of concentration

A plant cell has a 5% salt concentration. It is placed into a solution containing a 12% salt concentration.

What will happen to the plant cell?

• Water will move out of the plant cell, causing it to swell and burst.

• Water will move into the plant cell, causing it to shrivel.

• Water will move out of the plant cell, causing it to shrivel.

• Water will move into the plant cell, causing it to swell and burst.

Which of the following is true of diffusion?

• Diffusion of particles along the concentration gradient will occur until the particles move fully from one side of the solution to the other.

• Diffusion of particles along the concentration gradient will occur until particles are equally distributed in all areas of the solution.

• Diffusion of particles against the concentration gradient will occur until random motion occurs.

• Diffusion of particles against the concentration gradient will occur until all the particles have dissolved.
