Bacterial Flagella: Structure & Arrangement — NEET Biology
📚 Practice ConceptBacterial cells may be motile or non-motile. If motile, they have thin filamentous extensions from their cell wall called flagella. Bacteria show a range in the number and arrangement of flagella. Bacterial flagellum is composed of three parts – filament, hook and basal body. The filament is the longest portion and extends from the cell surface to the outside.
Match the following: Column I A. Pili B. Flagella (bacteria) C. Flagella (eukaryote) D. Cilia Column II i. Tubular protein structures for attachment ii. 9+2 microtubule arrangement iii. Filament-hook-basal body system iv. Short hair-like beating structures
