Auxin travels by diffusion towards:
Correct answer: D. Base of the plant
- A. Shoot
- B. Flowers
- C. Leaves
- D. Base of the plant
Explanation
Auxin is a plant hormone that is primarily produced in the shoot tips and young leaves. It travels downwards through the plant by the process of diffusion and active transport, primarily moving towards the base of the plant. This movement is crucial for processes such as cell elongation and root development. The other options are incorrect because auxin does not specifically travel towards the shoot, flowers, or leaves, but rather it moves downwards to the base for broader distribution and effect.

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.
