WebDec 24, 2024 · The cells are described as prokaryotic because they lack a nucleus. They exist in four major shapes: bacillus (rod shape), coccus (spherical shape), spirilla (spiral shape), and vibrio (curved shape). Most bacteria have a peptidoglycan cell wall; they divide by binary fission; and they may possess flagella for motility. WebThe length of rod-shaped bacteria is over 2–100 μm. Spiral-shaped bacteria occur in one of three forms: vibrio, spirillum, and spirochete (Fig. 7.1 c): (i) Vibrio. Vibrio are slightly curved or comma-shaped bacterial cells with less than one complete turn or twist in the cell, generally single and 2–3 μm long.
