Diffusion and Osmosis REVIEW

Movement across the cell membrane that does not require energy is called [ active / passive ] transport.

• active

• passive

The cell membrane is composed of proteins embedded in a [ phospholipid / molecular ] bilayer.

• phospholipid

• molecular

If there is a concentration gradient, substances will move from an area of high concentration to an area of [ equal / low ] concentration.

• equal

• low

The cell membrane is [ selectively permeable / impermeable ].

• selectively permeable

• impermeable

[ Equilibrium / Diffusion ] is the simplest type of passive transport.

• Equilibrium

• Diffusion

The diffusion of water through a selectively permeable membrane is called [ osmosis / diffusion ].

• osmosis

• diffusion

The direction of water movement across the cell membrane depends on the concentration of free water[ molecules / solutions ].

• molecules

• solutions

A solution that causes a cell to swell is called a [ hypertonic / hypotonic ] solution.

• hypertonic

• hypotonic
