Indeed, bacteria are classified on the basis of many characteristics. Cell shape, nature of multicell aggregates, motility, formation of spores, and reaction to the Gram stain are important. Those morphological features, including the shape and colour of bacterial colonies, are not always constant and can be influenced by environmental conditions.

Bacterial morphology deals with size, shape, and arrangement of bacterial cells. Size of Bacteria. Bacteria are microscopic organisms that are less than 3 micrometeres (μm) in size.

Although it is difficult to make a definite identification of cultures growing in broth or solid media many have distinguishing characteristics that give us clues to identification.

Bacteria are, in general one-tenth the size of the eukaryotic cell. On average, the size of bacteria ranges from 0.5 to 5 µm. However, they can be as tiny as 0.3 µm and as large as 0.7mm. The limit of resolution with the unaided eye is about 200 microns, and as many bacteria are smaller than this size, they are not visible with naked eyes.

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. Morphology of Bacteria: Bacteria are very small unicellular microorganisms ubiquitous in nature.
