The name of the microscopic organism that photosynthesises and has phlagellum is Euglena.
Euglena photosynthesizes using chloroplasts, which are organelles that contain chlorophyll and other pigments that absorb light energy. This energy is then used to convert carbon dioxide and water into glucose and oxygen.
The phlagellum in Euglena acts as a whip-like structure that helps the organism to move through its environment. It also helps in the process of photosynthesis by allowing the organism to position itself towards a light source.
Euglena can be found in a variety of aquatic environments, such as ponds, rivers, and streams. It can also be found in soil and on the surface of plants.
No, Euglena is not harmful to humans. It is a non-pathogenic organism and does not pose any known health risks to humans. In fact, it is commonly used in scientific research and as a food source for aquatic animals.
