Cell Transport CHALLENGE

This picture shows molecules of red dye that have moved. What is this type of movement called?

• Osmosis; the water molecules are moving from high concentration to low

• Diffusion; the dye molecules are moving from low to high concentration

• Diffusion; the dye molecules are moving from high to low concentration.

• Facilitated diffusion; because the molecules are moving through a protein channel.

This picture is a representation of what type of transport?

• Osmosis because it is diffusing through a protein from an area of high concentration to low concentration.

• Facilitated diffusion because it is diffusing through a protein from an area of high concentration to low concentration.

• Facilitated diffusion because it is diffusing through a protein from an area of low concentration to high concentration.

• Simple diffusion because it is diffusing through a protein from an area of high concentration to low concentration.

This a picture of an animal and plant cell placed in a solution. Describe the solution?

• It has a high solute concentration, like salt water

• It has a high water concentration, like pure, distilled water

• It has about the same amount of solutes as the cell

This a picture of an animal and plant cell placed in a solution. Describe the solution?

• It has a low solute concentration similar to tap water

• It has an equal amount of solute as inside the cell

• It has a high solute concentration similar to maple syrup

This plant was placed in a new vase with a solution. After a period of time, this is what happened. What occurred to the cells of this plant?

• Water rushed out of the cells due to the low water concentration of the outside solution.

• Solutes were drawn into the cells due to the high solute concentration.

• Water molecules were delivered to the cell's vacuole by diffusion.

• Solutes from the cells were lost to the outside solution due to osmosis.

In which case would a cell most likely shrink?

• when placed in a solution containing a high salt concentration
• when placed in a low solute concentration solution

• when placed in a solution containing a high water molecule concentration

• when placed in a solution containing pure, distilled water

A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. Which of the following has occurred?

• The swollen gums have absorbed the saltwater solution.

• The saltwater solution lowers the temperature of the water in the gums.

• The salt in the solution has moved against the concentration gradient.

• The water in the gums has moved out due to the high concentration of salt in the solution.

Look at the picture. What is most likely to occur over a period of time? (Choose 2)

• Oxygen will leave the cell.

• Oxygen will enter the cell.

• Carbon dioxide will leave the cell.

• Carbon dioxide will enter the cell.
