Possible technical applications inspired by subsystems of Euglena are given in 4.4.
4.3.1 Structural Overview
A schematic drawing of Euglena gracilis can be seen in Fig. 4.3. The motory
system of Euglena possesses two flagella, one of which emerges from the reservoir
(the emergent flagellum). The second is termed non-emergent flagellum. Attached
to the emergent flagellum, still within the reservoir is the photoreceptor, a proteic
crystal, located. Besides the reservoir the stigma can be found, (also called "eyespot"),
that consists of pigment granules (containing carotenoids), and is part of
the visual system.

Next to the stigma sits the contractile vacuole, that empties into the reservoir
