What is the structure of the cell membrane?

• Phospholipid bilayer

• Single layer of lipids

• Protein layer

• Carbohydrate layer

Which molecules can directly pass through the cell membrane?

• Small non-polar molecules

• Large polar molecules

• Charged ions

• Proteins

What is the process called when molecules pass through the cell membrane with the help of transport proteins?

• Facilitated diffusion

• Active transport

• Endocytosis

• Exocytosis

Match the following vocabulary terms and definitions.

• Isotonic

• Low concentration; the solution has less solutes than the cell, causing water to move into the cell and out of the solution.

• Hypertonic

• High concentration; the solution has more solutes than the cell, causing water to move out of the cell and into the solution.

• Hypotonic

• Same concentration; the solution and cell have equal concentration of solutes (particles), so water moves equally between the cell and solution.

What is the main function of the cell membrane?

• To produce energy

• To control what enters and leaves the cell

• To store genetic information

• To support the cell structure
