Open Ended

How does the Cell Membrane Permit Cellular Transport?

Fill in the Blanks

During diffusion, molecules move from a region of ___ concentration to a region of ___ concentration.

Open Ended

Write a summary explaining simple diffusion.

Fill in the Blanks

Facilitated diffusion requires the presence of

in the cell membrane to help move molecules across.

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.

Multiple Choice
