Passive Transport Quiz

What is diffusion?

• The process by which molecules or particles spread out from an area of low concentration to an area of high concentration.

• The process by which molecules or particles move in a random pattern without any specific direction.

• The process by which molecules or particles spread out from an area of high concentration to an area of low concentration.

• The process by which molecules or particles are absorbed by a solid or liquid substance.

Which of the following is an example of diffusion?

• Spreading of perfume in a room

• Spreading of light in a room

• Spreading of sound in a room

• Spreading of smoke in a room

What is osmosis?

• Movement of solvent molecules from an area of lower solute concentration to an area of higher solute concentration through a semipermeable membrane.

• Movement of solvent molecules from an area of higher solute concentration to an area of lower solute concentration through a semipermeable membrane.

• Movement of solute molecules from an area of higher solute concentration to an area of lower solute concentration through a semipermeable membrane.

• Movement of solute molecules from an area of lower solute concentration to an area of higher solute concentration without a semipermeable membrane.
