8.3 Cell transport (2)

Write your full name.

If a cell is placed in a solution with a higher concentration of solutes than inside the cell, what will happen to the cell?

• The cell will shrink.
• The cell will absorb more solutes.
• The cell will remain the same.
• The cell will swell and burst.

What role does ATP play in active transport?

• ATP is only used in passive transport.
• ATP provides the energy needed to move substances against their gradient.
• ATP is not involved in active transport.
• ATP is used to create a concentration gradient.

Which of the following best describes the process of osmosis?

• The movement of solutes from high to low concentration.
• The movement of water through a selectively permeable membrane.
• The active transport of ions across a membrane.
• The diffusion of gases in the lungs.

What is a common misconception about passive transport?

• Passive transport only occurs in plant cells.
• Passive transport moves substances against their concentration gradient.
• Passive transport does not require energy.
• Passive transport requires energy from ATP.

Which of the following best describes diffusion?

• The movement of water through a membrane.
• The active transport of ions.
• The movement of substances from high to low concentration.
• The movement of solutes against their gradient.

Which of the following statements about diffusion is true?

• Diffusion occurs only in liquid environments.
• Diffusion moves substances from low to high concentration.
• Diffusion requires energy input.
• Diffusion is a type of passive transport.

How does facilitated diffusion differ from simple diffusion?

• Facilitated diffusion requires energy, while simple diffusion does not.
• Facilitated diffusion uses transport proteins, while simple diffusion does not.
• Facilitated diffusion occurs only in plant cells, while simple diffusion occurs in all cells.
• Facilitated diffusion moves substances against their concentration gradient, while simple diffusion moves them with it.

Which type of passive transport involves the movement of water across a membrane?

• Osmosis
• Facilitated diffusion
• Simple diffusion
• Active transport
