How do shoots and roots demonstrate different responses in phototropism?

Shoots and roots exhibit different responses in phototropism due to their distinct roles and orientations. In shoots, particularly stems, phototropism involves positive growth towards the light source. This response ensures optimal exposure of leaves to sunlight for photosynthesis. In contrast, roots display negative phototropism, growing away from light. Root systems are more focused on anchorage and nutrient absorption, and growing away from light helps them navigate towards the soil, where they can efficiently explore and extract essential nutrients. The differential responses in phototropism highlight the specialized functions of shoots and roots in optimizing their interactions with the environment.
