The track is featured on their album "Phototropic" (1996). The flower stalk is initially positively phototropic and moves towards the light. It describes the phototropic and gravitropic properties of emerging shoots of monocotyledons. "C. coronatus" produces forcibly discharged sporangia, which show phototropic orientation. Additionally, these planulae exhibit negative phototropic behavior. When exposed to light, those germinants developed chlorophyll and were normally phototropic with continued elongation. This showed a positive phototropic response in the red light. The "nph1" and "npl1" double mutants were found to have reduced phototropic responses. The larvae are negatively phototaxic/phototropic, avoiding light and hiding in the substrate around them. After fertilisation, it becomes negatively phototropic and moves away from the light. The photoreceptors phytochromes A, B, C, D, and E mediate red light-based phototropic response. Different organs of the plant may exhibit different phototropic reactions to different wavelengths of light. They are seen from October to February, and are phototropic (turning towards the sun).
