d Question 27 Plant hormones are chemical regulators that stimulate or growth depending on their concentration and the type of tissue in which they are found. Based the information in the graph, which is a correct conclusion about plant hormones? STIMULATION GROWTH STEMS LOWHIGH HORMONE CONCENTRATION a They stimulate maximum stem growth at low concentrations ObThey most strongly inhibit root growth at low concentrations They stimulate maximum root growth and stern growth at the same concentration They stimulate maximum root and stem growth at different concentrations .

Answer 1

Based on the information provided in your question, the correct conclusion about plant hormones would be:

They stimulate maximum root and stem growth at different concentrations.

This conclusion is supported by the understanding that hormones can have varying effects on different tissues (roots vs. stems) depending on their concentration, which aligns with the idea that maximum growth for roots and stems occurs at different levels of hormone concentration.
