Detailed explanation-1: -The three basic shapes of bacteria are Cocci (round), Bacilli (rod), and Spirilla (spiral). When viewed under light microscope, most bacteria appear in variations of three major shapes: the rod (bacillus), the sphere (coccus) and the spiral type (spirillum).
Detailed explanation-2: -The three basic shapes of bacteria are bacillus (rod-shaped), coccus (spherical-shaped), and spirillum (spiral-shaped).
Detailed explanation-3: -Spiral-shaped bacteria occur in one of three forms: vibrio, spirillum, and spirochete (Fig.
Detailed explanation-4: -Rod-like bacteria maintain their cylindrical shapes with remarkable precision during growth. However, they are also capable to adapt their shapes to external forces and constraints, for example by growing into narrow or curved confinements.
Detailed explanation-5: -Bacteria are classified into five groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters.
