The fruit fly Drosophila melanogaster has been extensively studied for over a century as a model organism for genetic investigations. It also has many characteristics which make it an ideal organism for the study of animal development and behavior, neurobiology, and human genetic diseases and conditions.
In order to be classified as a plant or animal, an organism has to be multicellular, or made of more than one cell. Since it is a unicellular organism with some plant and animal characteristics, it is called a protist. Plant cells have walls. Thereâs no cell wall around a Euglenaâs cell membrane, so it is a protozoan. It used to belong to the kingdom Protista.
