Movement into and out of cells — practice question

When sucrose is transferred from the phloem sieve tube element to an actively dividing shoot tip, how do the water potential and the volume of solution in the phloem sieve tube element change?

  • Awater potential becomes higher; volume of solution decreases
  • Bwater potential becomes higher; volume of solution increases
  • Cwater potential becomes lower; volume of solution decreases
  • Dwater potential becomes lower; volume of solution increases
