EuglenaEuglena gracilis

• Actually, there are many species of Euglena, and I’m not quite sure what this one is. When we know the genus, but not the species, we write Euglena sp.

• Where “sp.” indicates species. If there are several different species we write spp for species plural.

• Autotroph– Euglena have chloroplasts that undergo photosynthesis using light energy to build sugar.

• Flagellum– The flagellum, or tail, helps the euglena move towards light and away from predators.

Eyespot– The Euglena has a very simple eye that senses light. This way the euglena can move untill it is in a lighted area.

• Nucleus – The nucleus is where all the DNA is stored. This is, of course, true for all eukaryotes, including members of the kingdom protista.
