Bacterial morphology is extremely diverse. Specific shapes are the consequence of adaptive pressures optimizing bacterial fitness. Shape affects critical biological functions, including nutrient acquisition, motility, dispersion, stress resistance and interactions with other organisms. Morphology of Bacteria: Bacteria are very small unicellular microorganisms ubiquitous in nature. They are micrometres (1μm = 10 -6 m) in size. They have cell walls composed of peptidoglycan and reproduce by binary fission. Recent work has established that bacterial morphology has an evolutionary history and has highlighted the survival value of different shapes for accessing nutrients, moving from one place to another, and escaping predators.

These are two groups depending upon the 2020-08-15 · Bacteria - Bacteria - Classification by morphology, biochemistry, and other features: Although genetic divergence highlights the evolutionary relationships of bacteria, morphological and biochemical features of bacteria remain important in the identification and classification of those organisms. Indeed, bacteria are classified on the basis of many characteristics. Cell shape, nature of Bacteria are difficult to see under the bright field microscope. Bacteria are almost colorless and therefore show little contrast with the medium in which they are suspended. => To visualize bacteria various dyes are used. Bacteria bear a slight negative charge => bind positively charged dyes (basic stains).

Spiral bacteria are another major bacterial cell morphology. Spiral bacteria can be sub-classified as spirilla, spirochetes, or vibrios based on the number of twists per cell, cell thickness, cell flexibility, and motility. Bacteria are known to evolve specific traits to survive in their ideal environment. Recent work has established that bacterial morphology has an evolutionary history and has highlighted the survival value of different shapes for accessing nutrients, moving from one place to another, and escaping predators.
