Passive Cell Transport

What is the main characteristic of Simple Diffusion in Cellville?

• It requires energy to move particles.

• It uses transport proteins to guide particles.

• It allows particles to move freely without energy.

• It only moves water molecules.

How does Facilitated Diffusion differ from Simple Diffusion?

• It requires energy to function.

• It uses transport proteins to guide particles.

• It only moves water molecules.

• It does not maintain balance.

What role do transport proteins play in Facilitated Diffusion?

• They provide energy for particle movement.

• They guide specific particles across the cell membrane.

• They move water molecules across the membrane.

• They prevent any particles from passing through.

What is the unique feature of Osmosis in the passage?

• It requires energy to move water molecules.

• It balances solute concentration by moving water.

• It uses transport proteins to move particles.

• It moves particles freely without energy.

Why are Simple Diffusion, Facilitated Diffusion, and Osmosis important to Cellville?

• They provide energy to the citizens.

• They are the lifeblood and maintain harmony in Cellville.

• They prevent any movement across the cell membrane.

• They only move water molecules.

Osmosis is the movement of

• 
  water from high concentration to low concentration

• water from low concentration to high concentration

• 
  sugar from high concentration to low concentration

• 
  sugar from low concentration to high concentration
