Abscisic Acid
Auxin
Which plant hormone is responsible for cell elongation and growth, especially in the shoot tips?
Auxin
Gibberellin
Cytokinin
Ethylene
What is the function of abscisic acid (ABA) in plants during periods of water stress?
Promotes stomatal opening
Promotes seed germination
Inhibits stomatal opening
Stimulates shoot elongation
What is the primary function of gibberellins in plants?
Root development
Flowering
Leaf senescence
Abscission
Which hormone plays a crucial role in the regulation of fruit development, particularly in promoting fruit setting and preventing premature fruit drop?
Cytokinin
Ethylene
Abscisic Acid
Gibberellin
Which plant hormone is involved in promoting seed germination and breaking dormancy?

Auxin
Brassinosteroids
Jasmonic Acid
Abscisic Acid
The 'Triple Response' in plants, including a reduction in stem elongation, thickening of stems, and horizontal growth, is associated with which hormone?
Auxin
Ethylene
Gibberellin
Abscisic Acid

Auxin
Gibberellin
Abscisic Acid
Cytokinin
