Movement into and out of cells — practice question

What changes happen to the water potential and to the volume of liquid in the phloem when sucrose is transferred from the phloem sieve tube to an actively dividing root tip?

  • Awater potential in phloem sieve tube becomes less negative; volume of liquid in phloem sieve tubes decreases
  • Bwater potential in phloem sieve tube becomes less negative; volume of liquid in phloem sieve tubes increases
  • Cwater potential in phloem sieve tube becomes more negative; volume of liquid in phloem sieve tubes decreases
  • Dwater potential in phloem sieve tube becomes more negative; volume of liquid in phloem sieve tubes increases
