Plant Hormones Quiz

Which of the following plant hormones is responsible for cell elongation and apical dominance?

• Cytokinins

• Gibberellins

• Auxins

• Ethylene

Gibberellins play a significant role in:

• Closing stomata

• Ripening fruit

• Stem elongation and breaking seed dormancy

• Inhibiting growth

Which hormone is mainly responsible for promoting fruit ripening?

• Auxins

• Abscisic acid

• Ethylene

• Cytokinins

Abscisic acid is known for:

• Stimulating seed germination

• Promoting flowering

• Inhibiting growth and closing stomata

• Enhancing cell division

Cytokinins are primarily produced in:

• Germinating seeds

• Cambial tissue and growing roots

• Ripening fruit

• Young leaves

You are given a cutting of a plant and want to ensure it develops roots. What hormone would you apply, and how would it help?

• Auxin - It promotes root development.

• Gibberellin - It enhances stem elongation.

• Cytokinin - It encourages shoot growth.

• Ethylene - It accelerates fruit ripening.
