Sentence examples for phototaxis from inspiring English sources

The photosynthetic colonies are usually organized so that cells with larger eyespots are grouped at one side to facilitate phototaxis (movement toward light) for photosynthesis, and the reproductive cells are grouped at the opposite side.

Sources that elicit a taxis response, which may cause a modification of speed, direction, or both, seem to encompass the entire range of environmental stimuli, such as gravity (geotaxis), temperature (thermotaxis), light (phototaxis), or chemicals (chemotaxis).
