Why are lateral buds often inhibited from sprouting even though a stem may be actively elongating?
A) The cells of lateral buds are more sensitive to auxin than stem cells.
B) Lateral buds are high in abscisic acid that prevents elongation.
C) Lateral 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 lateral buds are more sensitive to auxin than stem cells. Auxin produced by the apical meristem goes downward through the stem and inhibits the growth of the lateral buds because their cells are more sensitive to auxin than the cells of the stem. This process is known as apical dominance.
