Bacterial Cell Structures: Flagellum vs. Pili - Educational Illustration #3328926 (License: Personal Use)

The top bacterium features a single, whip-like flagellum used for swimming motility, while the bottom bacterium displays numerous hair-like pili involved in surface attachment, conjugation, and biofilm formation. Both are stylized prokaryotic cells with visible nucleoids and cytoplasmic granules, rendered in vibrant green with clean outlines for clarity in educational contexts.

Used in biology textbooks, online learning modules, and science websites to teach microbial anatomy, especially differences between flagella and pili. Matches user intent for visual aids in microbiology education.
