What is the final destination of the water lifted by the root?

Think it through first, then pick an option.

  1. a Epidermis
  2. b Sieve tube
  3. c Endodermis
  4. d Mesophyll tissue
Answer and explanation

Correct answer: d Mesophyll tissue

Water climbs from the root through the conducting tissue of the stem to the mesophyll tissue of the leaf.

Why the other options are wrong

  • a Epidermis: The epidermis is the outer covering; water does not end there.
  • b Sieve tube: The sieve tube belongs to phloem and carries food, not the water's destination.
  • c Endodermis: The endodermis is a layer midway along the route; water goes further.
