Cell Transport Quiz

Where is there a low concentration of perfume?

• in the bottle

• on the hand

• in the room

• in the top

What is passive transport?

• The movement of substances against the concentration gradient, requiring energy.

• The movement of substances across cell membranes without the need for energy.

• The process by which cells engulf substances from their external environment.

• The release of substances from cells into the external environment.

What happens to a cell placed in a hypertonic solution?

• The cell swells because water moves into the cell.

• The cell shrinks because water moves out of the cell.

• The cell remains the same size because the water movement is balanced.

• The cell divides due to the external pressure.

What is a hypotonic solution?

• A solution with a higher concentration of solutes outside the cell than inside.

• A solution with a lower concentration of solutes outside the cell than inside.

• A solution with equal concentration of solutes inside and outside the cell.

• A solution that prevents the movement of solutes across a membrane.

What does isotonic mean?

• The concentration of solutes is higher inside the cell than outside.

• The concentration of solutes is lower inside the cell than outside.

• The concentration of solutes is the same inside and outside the cell.

• The cell can freely change its concentration of solutes.

What is osmosis?

• The movement of solutes from an area of high concentration to an area of low concentration.

• The movement of the cell membrane to engulf substances.

• The diffusion of water across a selectively permeable membrane.

• The active transport of ions across the cell membrane.

What role does the cell membrane play in passive transport?

• It actively transports substances against the concentration gradient.

• It serves as a barrier to all substances, preventing their entry or exit.

• It allows certain substances to pass through while blocking others.

• It generates energy required for the transport of substances.

What happens to a cell in an isotonic solution?

• The cell swells as water enters.

• The cell shrinks as water exits.

• The cell maintains its shape and volume because the water movement is balanced.

• The cell divides rapidly due to equilibrium.

Why do cells placed in a hypotonic solution swell?

• Water moves out of the cell into the solution.

• Water moves into the cell from the solution.

• Solutes move out of the cell into the solution.

• Solutes move into the cell from the solution.

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

• Passive transport requires energy, while active transport does not.

• Active transport requires energy, while passive transport does not.

• Passive transport can only move substances in the direction of the concentration gradient.

• Active transport can move substances against the concentration gradient.
