Euglena have a red eyespot composed of carotenoid pigment granules. It is not thought to be photosensitive itself, but it filters sunlight that falls on a light-detective structure at the base of the flagellum, which only allows certain wavelengths to reach it. The eyespot partially blocks the light source as it rotates, which permits the Euglena find the light and move towards it. This process is known as phototaxis.

∙ 12y agoEuglenas are protists that are autotrophic. These means that they produce their own food. In order to do this, they must use photosynthesis. Therefore, euglena have light sensitive receptors in order to know where to move to carry out photosynthesis

What is the scientific name for euglena?
The scientific name for euglena is Euglena.
How do the eye spot and chloroplasts work together to help the euglena survive?
"The eye spot is a photo receptor. It alerts the Euglena to the presence of light. The chloroplast uses light to carry on photosynthesis. While the Euglena is in the presence of light it is making food. The Euglena also can eat food like other Protists if there is no light." quoted by ATP-Man (http://answers.yahoo.com/question/index?qid=20080114172048AAK4szq)

What are some special facts about euglena?
The euglena acts like a plant and an animal making it a unique organism. Euglena are single celled flagellate algae that can be found in the water, mud and sand of ponds and puddles. Although they contain chlorophyll, Euglena cannot survive solely by photosynthesis. Euglena vary in shape from cylindrical to oval, with flagella that are shorter than their bodies. They range in size from 35-45um and may be green or reddish in color.
