Diagram shows movement of molecule P through a plasma membrane. What conclusion can be made about the movement of P?

• Soluble in liquid

• Moves by osmosis

• Moves by active transport

• Moves by facilitated diffusion

A plant cell immersed in distilled water. What is process X?

• Facilitated diffusion

• Simple diffusion

• Active transport

• Osmosis
