The image below shows an example of topiary, an art form in which gardeners trim species of plants such as privet (Ligustrum ovalifolium) to form decorative shapes in gardens. The gardener is shown here on a ladder, trimming the upper parts of the topiary shape.
What phenomenon of plant growth allows such forms to be shaped in plants?
Negative geotropism
Cell differentiation in the shoot apex
Apical dominance
Production of the plant hormone indole-3-acetic acid (IAA)

Which row of the table gives the most accurate summary of the actions of auxins?
| In shoots | In roots | |
