Open Ended

Write a summary explaining simple diffusion.

Multiple Select

Which of the following are characteristics of facilitated diffusion?

• Requires energy

• Uses transport proteins

• Moves molecules from high to low concentration

• Moves only small molecules

Multiple Choice

Why do chemicals move from areas of high concentration to areas of low concentration across a cell membrane?

• To reach equilibrium

• To use more energy

• To increase concentration difference

• To prevent osmosis

Open Ended

Name 2 types of Passive Transport and explain the difference.

Multiple Choice

What is the main difference between a solute and a solvent in a solution?

• A solute is the substance being dissolved, while a solvent is the substance doing the dissolving.

• A solute is always water, while a solvent is always salt.

• A solute is the substance doing the dissolving, while a solvent is the substance being dissolved.

• A solute and solvent are always present in equal amounts.
