Question

Is IAA an auxin?

Answer 1

IAA (Indole-3-acetic acid):

1. Indole-3-acetic acid (IAA) is the most frequent auxin hormone found in nature.
2. It is produced in the apical buds of new leaves, as well as root tips and stems.
3. IAA controls cell division and elongation, tissue differentiation, apical dominance, and reactions to light, gravity, and pathogens, among other things.
4. IAA also acts as a signaling molecule that is required for the development of plant organs and growth coordination.
5. Changes in IAA levels elicit the maximum level of sensitivity from roots.

Final Answer: IAA belongs to the auxin class of plant hormones.
