Questions and Answers

What happens to animal cells in an isotonic solution?

  • They change shape as water moves into the cell
  • There is no concentration gradient and therefore, no net flow of water (correct)
  • The cells shrink and potentially burst
  • Water diffuses into the cell and causes it to swell
  • What is the effect of placing a cell in a hypotonic solution?

  • There is no change in osmotic pressure
  • Water will diffuse out of the cell and cause it to swell (correct)
  • The cells remain unchanged
  • The cell will shrink and crenate
  • How does osmotic pressure affect the shape of animal cells?

  • It has no impact on the cells
  • It causes the cells to change shape as water moves in or out (correct)
  • It causes the cells to shrink and crenate
  • It leads to no change in the shape of cells
  • What happens to a cell in a hypertonic solution?
