Question

Quizplus · Accepted Answer

The graph shows a clear correlation between plant height and gibberellin concentration, indicating that gibberellin plays a role in plant growth and development. The taller plants with higher concentrations of gibberellin also produce more fruit (pods), suggesting that gibberellin is involved in reproductive processes as well. The other choices are not supported by the data shown in the graph.
