I filled a tube with the Euglena medium (capacity: 15ml) and added about ten drops of Euglenas. To make the light colorful I cut out three stripes of transparent paper and wrapped them around the tube. I chose the fundamental colors yellow, red and blue. | I filled a tube with the Euglena medium (capacity: 15ml) and added about ten drops of Euglenas.

As a comparison I also prepared a tube without any paper. | As a comparison I also prepared a tube without any paper. | ||

I guess that the concentration will be very low behind the red and blue paper. As I read during my researches, Euglenas don’t react to red light. Blue is a pretty dark color and I think it won’t attract the organisms much. The yellow paper seems to be the most transparent, so my assumption is that the concentration will be the highest there. | I guess that the concentration will be very low behind the red and blue paper.
