Caption: Phototropism is a directional plant response to light. Plant shoots (stems) exhibit positive phototropism by growing towards a light source. These radish seedlings are bending towards the lamp because auxin hormones released into the far (dark) side of the stem causes elongation on that side.

Release details: Model release not required. Property release not required.
