Osmosis describes the movement of (a)   across the semipermeable membrane.

• gas

• water
• glucose

• proteins

Diffusion is the movement of particles (a)   .

• from low to high concentration

• from high to low concentration
• from equilibrium to areas of high concentration

• all of the above

Controlling what goes into or out of the cell without energy is called (a)   .

• active transport

• endocytosis

• passive transport
• exocytosis

The function of the cell membrane is to ​ (a)   .

• break down cellular waste
• make proteins
