Cell Transport Assessment S25

The diffusion of water molecules through a selectively permeable membrane is:

• Homeostasis

• Osmosis

• Active Transport

• Equilibrium

The movement of molecules from a place where there is a greater/higher concentration to an area where there is lesser/lower concentration is:

• Homeostasis

• Diffusion

• Endocytosis

• Active Transport

A selectively permeable membrane

• allows all substances to enter and leave

• prevents all substances from entering or leaving

• allows certain size substances to enter and leave

• allows only waste materials to leave

A solution in which the concentration of solutes is the same inside and outside of a cell is a _____________________ solution.

• hypertonic

• hypotonic

• isotonic

• homeotonic

If a red blood cell is placed in a solution that has a concentration gradient higher than the red blood cell, this type of solution is called:

• Isotonic

• Hypotonic

• Hypertonic

• Homeotonic

If a red blood cell is placed in a hypotonic solution, it will eventually

• shrink up

• swell and burst

• no change will occur

• swell and not burst

The difference in the concentration of a substance across a space is called:

• kinetic energy gradient

• solvent gradient

• concentration gradient

• dynamic equilibrium

A cell that is 90% water and 10% solute is placed in a solution that is 90% water and 10% solute. Which of the following is correct?

• it is hypertonic because water is exiting the cell.

• it is isotonic because the concentration is the same inside and outside the cell.

• it is hypotonic because water is entering the cell.

• it is hypertonic because water is entering the cell.

A cell that is 80% water and 20% solute is placed in a solution that is 60% water and 40% solute. Which of the following is correct?

• It is isotonic because the concentration is the same inside and outside the cell.

• It is hypertonic because water is exiting the cell.

• It is hypotonic because water is entering the cell.

• It is hypertonic because water is entering the cell.
