Questions and Answers

What is the main characteristic of passive transport?

  • The movement is from an area of lower concentration to an area of higher concentration
  • It involves the diffusion of water through a selectively permeable membrane
  • It requires energy
  • The movement of molecules is from an area of higher concentration to an area of lower concentration (correct)

What happens when a cell is placed in a hypertonic solution?

  • The cell swells due to an influx of water
  • Water moves from inside the cell into the solution, causing the cell to shrink (correct)
  • Water moves equally in both directions and the cell remains the same size
  • The solution has a lower concentration of solutes and a higher concentration of water than inside the cell

What is the result of osmosis?

  • Water moves from an area of high concentration to an area of low concentration
  • The movement of particles down their concentration gradient
  • The diffusion of water through a selectively permeable membrane (correct)
  • Water moves equally in both directions and the cell remains the same size
