Euglena flagellate protozoan. Computer artwork of the flagellate protozoan Euglena gracilis. This freshwater single-celled organism can either obtain energy from sunlight,via photosynthesis,or by absorbing chemicals from its surroundings. Cell organelles called chloroplasts (green) are used for photosynthesis. A sensory organ,known as the eye spot,or stigma (pink),is able to perceive the intensity of light. This allows E. gracilis to move,using its tail-like flagellum (top),to the areas of most intense light. Also seen is the nucleus (purple),which contains the cell's genetic information | |
