Question 3 • AISD-Biology B CR (25-26)
Cutting a stem can reduce apical dominance, allowing hormones to stimulate lateral buds and leaf growth. Plant hormones also control some tropisms, such as auxin’s role in bending toward light or responding to gravity. Auxin promotes cell elongation where it accumulates, while buds generally remain dormant in winter, and auxin is not the only hormone involved in plant development.
