Caption: Phototropism is a directional plant response to light. Plant shoots (stems) exhibit positive phototropism by growing towards a light source. This bean plant, Phaseolis vulgaris, is 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.
