The illustration depicts a bacterial flagellum, highlighting its structure composed of several segments. The structure includes an anchoring base in red, extending outward with connections in green and a long filament section in cyan. The flagellum is an essential appendage granting motility to bacterial cells. The predominant colors include red, green, and cyan, indicating different structural components of the flagellum. This diagram is crucial for understanding microbial propulsion mechanisms in prokaryotic cells.
