Why are axillary buds often inhibited from growing even though a stem may be actively elongating?
A) The cells of axillary buds respond differently to auxin than stem cells.
B) Axillary buds are high in abscisic acid that prevents elongation.
C) Axillary buds are low in gibberellins.
D) Stem cells lack receptors for auxin.
E) Stem cells can overcome auxin inhibition with high levels of gibberellins.

Question

Quizplus · Accepted Answer

The cells of axillary buds respond differently to auxin than stem cells, which causes them to be inhibited from growing even when the stem is actively elongating. This is because the auxin produced by the apical meristem (located at the tip of the growing stem) inhibits the growth of axillary buds, while promoting the elongation of the stem.
