Bacterial Cell Structure Diagram | Microbiology Illustration #3742213 (License: Personal Use)

The top bacterium is depicted with a single polar flagellum, indicating motility, while the bottom bacterium features numerous hair-like pili surrounding its surface, used for attachment and horizontal gene transfer. Both cells show three internal circular structures representing nucleoids or plasmids, rendered in a clean, cartoon-style vector illustration for educational clarity.

This image is commonly used in microbiology textbooks, online courses, and science education websites to teach basic bacterial anatomy and differentiate functional surface appendages. It serves users seeking visual aids for understanding prokaryotic cell structures.
