Why can the same plant hormone show different effects in a root and a stem?
Answer and explanation
Correct answer: Because different organs have different sensitivities and functions
A plant hormone acts according to its concentration, the tissue receiving it, and that tissue’s sensitivity and developmental state. Roots and stems have different structures, functions, and optimal hormone concentrations. Consequently, the same hormone may stimulate growth in one organ but inhibit or alter growth in another. Option A expresses this principle. The remaining choices are incorrect because roots and stems have different functions, plants are cellular, and hormones are not restricted to air.
