Passive Transport Quiz

What is passive transport?

• Movement of particles through the cell membrane using energy

• Movement of particles through the cell membrane with the help of specialized protein channels

• Movement of particles from high to low concentration without using energy

• Movement of particles from low to high concentration using energy

Which of the following is not a type of passive transport?

• Diffusion

• Osmosis

• Active transport

• Facilitated diffusion

What is the function of a semi-permeable cell membrane in passive transport?

• To create a barrier for all particles

• To facilitate the movement of particles

• To allow only certain sized particles to pass through

• To prevent the movement of particles

What is the process of achieving a state of equilibrium in passive transport?

• Particles move from low concentration to high concentration

• Particles move from high concentration to low concentration

• Particles move randomly

• Particles stop moving

Which example best represents diffusion?

• A ball rolling down a hill

• A ball staying still

• A ball rolling up a hill

• A ball moving in a circle

What is the main difference between osmosis and diffusion?

• Diffusion involves movement of water molecules, while osmosis does not

• Osmosis requires energy, while diffusion does not

• Osmosis involves movement of water molecules, while diffusion does not

• Diffusion requires energy, while osmosis does not
