Which one is present in the fruit of the stimulus?
Think it through first, then pick an option.
- a Ethylene
- b Auxin
- c Gibberellin
- d Cytokinin
Answer and explanation
Correct answer: d Cytokinin
Cytokinin is found in fruit, grain and the water of the coconut.
Why the other options are wrong
- a Ethylene: Ethylene ripens fruit; the book does not name it as the hormone of coconut water.
- b Auxin: Auxin goes with stem growth and rooting; for coconut water the book names cytokinin.
- c Gibberellin: Gibberellin lengthens the stem; it is not the hormone of coconut water.
