Bacteria, also called germs, are microscopic organisms not visible with the naked eye. ... Bacteria are single-celled, or simple, organisms. Morphology or shape of a bacteria cell is the most distinguished property of bacteria. Morphology of bacteria cell not only tells the shape but also decides its pathogenicity. Morphological traits of a bacteria cell are an important factor in its adaptability and evolution. There are many features like motility, mode of nutrition, that are affected by the shape of bacteria. The three basic bacterial shapes are coccus (spherical), bacillus (rod-shaped), and spiral (twisted), however pleomorphic bacteria can assume several shapes. The presentation gives in-depth knowledge on the topic.
