Bacterial Cell Structure Diagram - Anatomy of a Prokaryotic Cell #223368 (License: Personal Use)

This scientific illustration depicts a Gram-negative bacterial cell in cross-section, revealing outer membrane, peptidoglycan layer, periplasmic space, cytoplasmic membrane, nucleoid region with circular DNA, scattered ribosomes, and plasmids. Surface appendages include multiple pili (for adhesion/conjugation) and a single polar flagellum for motility; the scale bar indicates 1000 nanometers. The orange outer membrane and purple pili contrast with green plasmids and gray nucleoid to aid visual learning.

Used in microbiology textbooks, educational websites, university lecture slides, and science outreach materials to teach prokaryotic cell anatomy; matches user intent for understanding bacterial morphology, virulence factors, or comparative cell biology.
