Which one plays the greater part in carrying water and mineral salt?
Think it through first, then pick an option.
- a Tracheid
- b Sieve cell
- c Vessel
- d Companion cell
Answer and explanation
Correct answer: c Vessel
Carrying water and mineral salt and giving firmness is the main job of the vessel.
Why the other options are wrong
- a Tracheid: A tracheid also carries sap, but carrying water and mineral salt is the vessel's main job.
- b Sieve cell: A sieve cell carries food, not water. The right answer here is: Vessel.
- d Companion cell: The companion cell helps the sieve cell; it does not carry water.
