Chapter 24.5, Problem 2MC
Summary Introduction
To determine:
The role of auxin in phototropism.
Concept introduction:
Phototropism is the phenomenon in which, the orientation of a plant part away or towards the direction of light. This process is controlled by the photoreceptor molecules, which are responsible for detecting wavelength and intensity of the light.

How does the signal transduction pathway for auxin that leads to cell wall loosening. Include the receptors ABP and ARF.
How does the auxin pathway possibly differ from the 'generic' signal transduction pathway? Consider expressing the cellular components that differ in the absence and presence of auxin.
