Nov 5, 2007 The discussion of bacterial morphology has been domi- nated by questions about how a cell manages to create a rod shape, which, of course, is

INTRODUCTION • Bacteria is unicellular, free-living, microscopic microorganisms capable of performing all the essential functions of life. • They possess both deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA). • Bacteria are prokaryotic microorganisms that do not contain chlorophyll.

Morphology of bacteria

They are found everywhere in air, water, soil, and bodies of organisms. There is no natural death of bacteria. They are killed either using chemicals or by infecting with virus. Both bacteria and cyanobacteria are.prokaryotic-Bacteria come in three basic shapes:2., Coccus , bacillus.and spirillumAlmost all eubacteria are heterotrophs and obtain-3nutrition from outside sources. Many of thesebacteria are saphrophytic and live by causing decayand putrification of organic material. Morphology of bacteria Bacteria can be distinguished from one another by their morphology: size, shape, arrangement, staining characteristics.

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).

Bacteria are very small microorganisms which can be visualized only under microscope. They are stained by staining reagents & then visualized under high magnification power of compound microscope. They are having size range in microns. Each bacterial cell measures about 1.25 – 2 µm in diameter & 2-10 µm in length.

It is the characteristic property of a particular species. 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.

In prokaryotes, the primary function of the cell wall is to protect the cell from internal turgor pressure caused by the much higher concentrations of proteins, and other molecules inside the cell compared to its external environment.

The usual bacteria that you see range in size from 0.5 to nearly 10 microns (a few Hence, a colony of bacteria is a clone of genetically alike bacteria.

ADVERTISEMENTS: Here are your useful notes on the morphology of bacteria! Size: The bacterial cells vary greatly in their size. An average cylindrical bacterial cell measures 3μ long and 1μ broad whereas an average spherical cell is 1μ in diameter. The average volume of a bacterial cell is 1 cubic micron. According to Buchanan and […]

in an 'unstained wet film') In this way their general shape can be seen and their motility determined. Depending on their shape, bacteria are classified into several varieties Cocci (from kokkos meaning berry) are spherical or oval cells Bacilli (from baculus meaning rod) are rod-shaped cells staining; and 3) will retain the original cell morphology after fixation and staining. After you have stained your bacterial smears, you will examine them with the oil immersion lens, noting the morphological and staining characteristics of each species.

These strains are, by morphological Many of their morphological and physiological properties are similar, and of included rod-shaped bacteria H. halobium.
