Bacterial Cell Shapes: Cocci, Bacilli, and Spirilla Explained #20298 (License: Personal Use)

The image is a scientific illustration divided into three vertical panels, each depicting a distinct bacterial morphology. The left panel shows cocci-spherical cells that often form clusters or chains; the middle panel displays spirilla, characterized by their helical or corkscrew shapes; and the right panel illustrates bacilli, which appear as elongated rods, some straight and others slightly curved. These forms are fundamental to bacterial identification and taxonomy in microbiology.

Used in educational biology or microbiology web pages, textbooks, and online courses to teach basic bacterial morphology. Matches user intent for learning foundational microbiology concepts, especially for students or educators seeking visual aids for classification.
