Unlike other algae genera sequenced to date, these swift swimmers can cut through the water column at a rate of 50 body lengths per second, and are phototactic, meaning that they can swim towards the sunlight from which they derive their energy.
Isopods are negatively phototactic (reathey ct to light by moving away from it), and usually remain hidden under rocks and debris.
The results demonstrated that in free-swimming spheroids, only those cells of the anterior hemisphere that face toward the light source reverse the beating direction in the presence of illumination; this behavior results in phototactic turning.
Our results also indicate how recently evolved multicellular organisms adapted the phototactic capabilities of their unicellular ancestors to multicellular life.
On the basis of our results, we developed a mechanistic model that predicts the phototactic behavior in V. rousseletii.
In this study, the phototactic behavior in the spheroidal, multicellular volvocine green alga Volvox rousseletii (Volvocales, Chlorophyta) was analyzed.
Many moths are attracted to light (a condition known as being positively phototactic).
