Detailed explanation-1: -Rod-shaped bacteria are termed bacilli. These bacilliform bacteria are found in several taxonomic groups of bacteria. The term Bacillus (genus) includes rod-shaped gram-positive bacteria. Bacilli also comprise several other such genera.

Detailed explanation-2: -Bacillus species are rod-shaped, endospore-forming aerobic or facultatively anaerobic, Gram-positive bacteria; in some species cultures may turn Gram-negative with age. The many species of the genus exhibit a wide range of physiologic abilities that allow them to live in every natural environment.

Detailed explanation-3: -Bacillus bacteria is a rod-shaped bacteria.

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: -A rod shaped cell has a streamlined body which would be advantageous in swimming, just like the slender body of a fish, a boat or a plane. A spherical body will experience greater frictional resistance. This hypothesis is supported by the fact that among the flagellated motile bacteria almost all are rod shaped.
