Osmosis and Diffusion Concepts Explained

What is the term used to describe the movement of molecules from an area of high concentration to an area of low concentration?

• Facilitated Diffusion

• Diffusion

• Active Transport

• Osmosis

What does equilibrium mean in the context of diffusion?

• When molecules stop moving

• When molecules are equally distributed

• When there is a high concentration

• When there is a low concentration

Which of the following is an example of diffusion?

• Water moving through a membrane

• Food dye spreading in water

• Salt dissolving in water

• Sugar dissolving in tea

What is osmosis specifically the movement of?

• Air

• Water

• Food dye

• Salt

Through what type of membrane does osmosis occur?

• Impermeable membrane

• Semipermeable membrane

• Solid membrane

• Flexible membrane

What is facilitated diffusion?

• Diffusion without any help

• Diffusion with the help of a transport protein

• Active transport of molecules

• Movement of water through a membrane

Which type of molecules typically require facilitated diffusion?

• Polar molecules

• Small molecules

• Gaseous molecules

• Non-polar molecules

What is passive transport?

• Transport that requires energy

• Transport that does not require energy

• Transport of water only

• Transport of large molecules only

Which of the following is an example of passive transport?

• Osmosis

• Active transport

• Facilitated diffusion

• Both osmosis and facilitated diffusion

What is required for active transport to occur?

• Oxygen

• ATP

• Water

• No energy
