Bacterial Cell Morphology Diagram - Types of Bacteria Shapes #177408 (License: Personal Use)

This educational line drawing illustrates six primary bacterial morphological types: diplococci (paired spheres), streptococci (chains of spheres), bacilli (single rods), vibrios (curved rods), spirilla (tight helices), and a polar-flagellated bacillus. Each cell is rendered with textured shading to indicate surface detail, and flagellar structures are shown for motility examples.

Used in biology textbooks, university microbiology lectures, and online educational resources to teach bacterial classification by shape; supports user intent for learning foundational microbiology concepts.
