Question

what is the role of growth hormone in plants movements​

Answer 1

Answer:

Explanation:

Example: Indole Acetic Acid (IA). Auxin is a plant hormone produced in the stem tip that promotes cell elongation. ... This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance.

Answer 2

Answer:

Auxin and cytokinin are critical growth hormones in plant development and are naturally present within the plant at variable concentrations throughout the season. Their presence and activity are different from other hormones which act more in an on-off manner and are present only at specific times.
