Correct answer: D. Indole acetic acid.Scheduling Virtual Doctor Consultations
- A. Indole propionic acid.
- B. Indole carboxylic acid.
- C. Indole acetaldehyde
- D. Indole acetic acid.Scheduling Virtual Doctor Consultations
Explanation
The principal natural auxin is indole-3-acetic acid, commonly written as indole acetic acid or IAA. Indole propionic acid is chemically similar in name, so students may select it, but it is not the usual primary auxin identified in basic biology.

About Chemical Coordination and Hormones
Chemical coordination uses hormones released by endocrine glands and carried in blood to specific target cells. Coverage includes the pituitary, thyroid, pancreas, adrenal glands, ovaries and testes, feedback control, and the contrast between slower, longer-lasting hormonal responses and rapid nervous coordination.
