Detailed explanation-1: -No, you do not find the same amount of auxin in all the tissues of a plant. In fact, the uneven auxin distribution is a key factor for proper development. IAA concentrations can differ by an order of magnitude between shoot and root and appear highest in meristems located at the tip of the roots and the shoots.
Detailed explanation-2: -→How does auxin play a role in phototropism? Auxin is responsible for promoting elongation on the shaded side of a plant stem. This allows the stem to grow towards the light source. The hormone accumulates on the shaded side, causing cells on that side to grow longer and thus bending the stem towards the light.
Detailed explanation-3: -The Auxin Distribution in the Root Tip Is Due to the Interplay between PIN and AUX1/LAX-Mediated Active Transport. Auxin is a key regulator of plant growth and development. Within the root tip, auxin distribution plays a crucial role specifying developmental zones and coordinating tropic responses.
