What is the role of auxins in apical dominance?
Correct Answer: Auxins inhibit the growth of lateral buds, maintaining apical dominance in plants.
- Step 1: Understand that auxins are a type of plant hormone.
- Step 2: Know that apical dominance is when the main shoot of a plant grows more than the side shoots.
- Step 3: Learn that auxins are produced at the tip of the plant (the apical bud).
- Step 4: Realize that auxins travel down the plant and affect growth.
- Step 5: Understand that auxins inhibit (stop) the growth of lateral buds (side shoots).
- Step 6: Conclude that by inhibiting lateral buds, auxins help the main shoot grow taller, maintaining apical dominance.
