Cell Transport - EOC Review

A bag of starch solution is immersed in a beaker of water and iodine. The bag is selectively permeable to iodine What will MOST influence the net movement of iodine?

• temperature

• concentration

• volume

• pH

The selectively permeable nature of cell membranes allow them to maintain

• homeostasis

• weight

• disequilibrium

A potato is placed in a beaker of pure water. What will happen to the potato after a few hours?

• turn dark blue

• produce a gas

• lose mass and volume because water will move out

• gain mass and volume because water will move in

A freshwater plant is placed in a container of saltwater. What will most likely happen to the calls of the plant?

• They will swell because water will move into them.

• They will swell because salt will move into them.

• They will shrink because water will move out of them.

• They will shrink because salt will move out of them.

What will happen if the concentration of water is the same inside as outside a cell?

• net movement of water out of the cell and the cell will shrink

• net movement of water in to the cell and the cell will swell

• water will move in and out with no cell change

• water will not move in or out of the cell and there will be no cell change

If energy is needed to move materials into or out of a cell, what is most likely occurring?

• active transport

• passive transport

• osmosis

• diffusion

In the human body, oxygen is absorbed by the lungs and nutrients are absorbed by the small intestine. In a single-celled organism, this absorption directly involves the

• nucleus

• cell membrane

• chloroplasts

• chromosomes

If the concentration of sodium is greater outside a cell than inside the cell, which process would move sodium out of the cell?

• diffusion

• carbohydrate synthesis

• active transport

• osmosis

A root hair cell may continue to absorb minerals even though the cytoplasmic concentration of these minerals is greater inside the cell than in the soil. This absorption is accomplished chiefly as a result of?

• passive thransport

• diffusion

• osmosis

• active transport

A red blood cell placed in distilled water will swell and burst due to the diffusion of

• salt from the red blood cell into the water

• water into the red blood cell

• water from the blood cell into its environment

• salt from the water into the red blood cell.
