Euglena flagellate protozoa. Computer artwork of the flagellate protozoa Euglena gracilis. These freshwater single-celled organisms can either obtain energy from sunlight,via photosynthesis,or by absorbing chemicals from their 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,to the areas of most intense light. Also seen are the nuclei (purple),which contain the cells' genetic information | |
