Red blood cells and a Virus

Out of all the types of microorganisms I would like to refer to three today. First one is bacteria, which are prokaryotes, living things that are neither plants nor animals, but belong to a group all by themselves. Typically they have a wide range of shapes, ranging from spheres to rods and spirals. Another microorganism is a virus as seen in the picture above in purple. A virus is an infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host. Last, microorganism is a fungi which can be unicellular, multicellular, or syncytial spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools.
