Cell Membrane Transport Quiz

What is the primary function of the cell membrane?

• To provide energy to the cell

• To control the movement of substances in and out of the cell

• To store genetic information

• To produce proteins

Which process involves the movement of water molecules across a semi-permeable membrane?

• Active transport

• Osmosis

• Endocytosis

• Facilitated diffusion

What is the main difference between active transport and diffusion?

• Active transport requires energy, while diffusion does not

• Diffusion requires energy, while active transport does not

• Both require energy

• Neither requires energy

Which of the following is an example of facilitated diffusion?

• Oxygen moving into a cell

• Glucose entering a cell through a protein channel

• Water moving out of a plant cell

• Sodium ions being pumped out of a cell

What is the role of protein channels in the cell membrane?

• To provide structural support

• To facilitate the movement of large or charged molecules

• To store nutrients

• To produce energy

Which process involves the cell membrane engulfing large particles to bring them into the cell?

• Exocytosis

• Endocytosis

• Osmosis

• Diffusion

In plant cells, what happens to the cell when placed in a hypotonic solution?

• The cell shrinks

• The cell remains the same

• The cell swells and becomes turgid

• The cell bursts

Which of the following is NOT a method of active transport?

• Sodium-potassium pump

• Endocytosis

• Osmosis

• Exocytosis

What is the primary component of the cell membrane that forms a barrier to most substances?

• Proteins

• Lipids

• Carbohydrates

• Nucleic acids

Which process involves the expulsion of materials from a cell?

• Endocytosis

• Exocytosis

• Diffusion

• Osmosis
