Bacteria and Archaea are classified by direct examination with the light microscope according to their morphology and arrangement. The basic morphologies are spheres and round-ended cylinders. But there may be others such as helically twisted cylinders, cylinders curved in one plane and unusual morphologies. Arrangements include pairs, tetrads, clusters, chains and palisades.

Arrangement Of Cells – Pseudomonas aeruginosa is arranged singly or in pairs. Motility – Pseudomonas aeruginosa is an actively The morphology of bacteria can be studied in the first place by examining them microscopically in the unstained condition, suspended in a thin film of fluid between a glass slide and coverslip (i.e. in an 'unstained wet film') In this way their general shape can be seen and their motility determined.

Cell shape, nature of Characteristics of bacterial colonies Colony morphology can sometimes be useful in bacterial identification. Colonies are described on the basis of size, shape, texture, elevation, pigmentation, and effect on growth medium. In this blog post, you will find common criteria that are used to characterize the bacterial growth. This General Microbiology video gives an explanation of the different bacterial morphologies. 2021-03-13 · Morphology of Bacteria: Antonie Van Leeuwenhoek was the first to describe the morphology of bacteria.

Bacteria and Archaea are classified by direct examination with the light microscope according to their morphology and arrangement. The basic morphologies are spheres (coccus) and round-ended cylinders (bacillus). The unit of measurement used in bacteriology is the micron (micrometer) which is one-thousandth of a millimeter. 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.
