Which Plant Hormones Would Likely Be Found in High Amounts

Question

Which plant hormones would likely be found in high amounts in a sprouting vegetative stem?
A) auxins, gibberellins, cytokinins
B) gibberellins, brassinosteroids, cytokinins
C) auxins, abscisic acid, ethylene
D) auxins, phytochrome, brassinosteroids
E) gibberellins, cytokinins, abscisic acid

Accepted Answer

Auxins, gibberellins, and cytokinins are all plant hormones that promote growth and development, which are necessary for the sprouting of a vegetative stem. Gibberellins and cytokinins are particularly important for cell division and elongation, which are necessary for stem growth, and auxins can also promote stem elongation by loosening cell walls. Therefore, these hormones are likely to be found in high amounts in a sprouting vegetative stem.
