Movement into and out of cells — practice question

What takes place in the sieve tube elements of a photosynthesising leaf and an actively growing root?

  • Asieve tube elements in leaf: water potential decreases; sieve tube elements in root: sugars are moved in
  • Bsieve tube elements in leaf: water potential decreases; sieve tube elements in root: sugars are moved out
  • Csieve tube elements in leaf: water potential increases; sieve tube elements in root: sugars are moved in
  • Dsieve tube elements in leaf: water potential increases; sieve tube elements in root: sugars are moved out
