Question

Quizplus · Accepted Answer

Auxin is a plant hormone that can have different effects at different concentrations. At low concentrations, it stimulates cell elongation in apical meristems, while at high concentrations, it inhibits the growth of axillary buds. This is an example of how plant hormones can have different effects depending on their concentration.
