The given diagram shows a stem tendril helping a plant to climb up a support.The type of growth movement exhibited by the plant is
Correct answer: B. Nutation
- A. Epinasty
- B. Nutation
- C. Hyponasty
- D. Nyctinasty
Explanation
Nutation is a type of growth movement where a plant part, such as a stem or tendril, exhibits revolving or spiraling motion. The tip of a climbing plant's stem or tendril may sway back and forth (nutation) as it searches for a support. So option B is correct. All other processes are not related to the climbing movement shown.

About Plant Growth Regulators
Plant growth regulators are chemical messengers that control growth, development and responses to the environment. The topic covers auxins, gibberellins, cytokinins, abscisic acid and ethylene, including cell elongation, apical dominance, tropisms, seed germination, dormancy, fruit ripening and leaf fall, with growth promoters distinguished from inhibitors.
