What is the main structure of the cell membrane called?

• Lipid Bilayer

• Protein Channel

• Carbohydrate Layer

• Nucleic Acid Layer

Why do the non-polar tails of phospholipids hide from water in the bilayer structure?

• They are attracted to water

• They are repelled by water

• They dissolve in water

• They form bonds with water

How are the phospholipids arranged in the bilayer to interact with water?

• Polar heads face inward, tails face outward

• Both heads and tails face outward

• Polar heads face outward toward water, tails face inward away from water

• Tails and heads are randomly arranged

Which type of transport in cells does NOT require energy?

• Passive Transport

• Active Transport

• Facilitated Diffusion

• Endocytosis

What is the main difference between passive transport and active transport in cells?

• Passive transport uses energy, active transport does not.

• Active transport uses energy, passive transport does not.

• Both use energy.

• Neither uses energy.

• Osmosis

Which of the following is a type of passive transport?

• Protein Pumps

• Endocytosis

• Diffusion

• Exocytosis

Which of the following is an example of passive transport that involves water movement?

• Endocytosis

• Osmosis
