The euglena is a flagellate that can complete photosynthesis if exposed to direct light, and that loses its photosynthetic pigments if kept in the dark and starts feeding on dead organic matter. Once back to light, the euglena starts photosynthesis again. The Figure clearly shows the chloroplast, the organelles in which photosynthesis takes place. The flagellum is used to move in a wave-like motion. The spiracle is a pigment-rich area, probably associated with the photoreceptor.

Q: What happens when Euglena is placed in darkness? Write your answer Related questions. What would happen to euglenas color if it were placed in darkness for a long period of time? Is euglena plant like or animal like? What is the behavior of a Euglena? These colourless flagellates live only in water rich in organic materials such as the fluid in the puddles round cowsheds. They absorb the organic substances from their environment and use them as food, i.
They cannot, however, build up starch from carbon dioxide. Other colourless flagellates are able to take in solid particles of food material and digest them in a way described in the section dealing with Paramecium.
