How do microbiologists identify bacterial shapes and cell arrangements​?
Microbiologists identify bacterial shapes and cell arrangement by their own structure in the microscope because Bacteria are unicellular prokaryotic bacteria that lack chlorophyll pigments. Because there is no nucleus or membrane-bound organelles, the cell structure is simpler than that of other species.
Bacteria maintain a defined form due to the existence of a hard cell wall, even when their shape, size, and structure change. Most bacteria have one of three primary morphologies when seen under a light microscope: the rod (bacillus), the sphere (coccus), or the spiral variety (vibrio). The bacterial structure is divided into two parts: organization and form. It can be paired (diplo), grape-like clusters (staphylo), or chains in terms of organization (strepto). Rods (bacilli), Spheres (cocci), and Spirals are the most common shapes (spirillum).
