What carries the substance mentioned in the plant?

Think it through first, then pick an option.

  1. a Sieve cell
  2. b Vessel
  3. c Companion cell
  4. d Phloem parenchyma
Answer and explanation

Correct answer: b Vessel

The water given to the pot climbs through the xylem vessels and revives the leaves.

Why the other options are wrong

  • a Sieve cell: The sieve cell carries food, not water. The right choice is: Vessel.
  • c Companion cell: The companion cell helps the sieve tube; it does not transport water.
  • d Phloem parenchyma: Phloem parenchyma deals with food, not water.
