For example Sarcina aurantiaca, Sarcina lutea, and Sarcina ventriculi. The common characteristic associated with these organisms is being a strict anaerobe. This occurs when the cells divide in a perpendicular plane. In this formation, the bacterial cells form a group of eight cells. Examples are Aerococcus, Pediococcus, and Tetragenococcus. This arrangement results when the cells divide into four planes. Tetrad bacteria are arranged in a group of four cells that remain attached and grow in the attachment after division. Examples Streptococcus pneumonia, Moraxella catarrhalis, Enterococcus spp, and Neisseria gonorrhea. Some of the cells in this appointment might stay spherical while some might appear flattened, elongated, or bean-shaped. This arrangement results when two bacterial cells happen as a pair( joined together). A coccus is any bacterium or archaeon that has a spherical, ovoid, or commonly round shape. This group contains bacteria that are present as a single cell. What are the arrangements of Cocci?Ĭocci bacteria can be arranged either singly, in pairs, in groups of four, in chains, clusters, or cubes consisting of eight cells. It is assumed that coccoid forms were derived from rod-shaped organisms throughout evolutionary time. They appear flattened when placed in groups. These may either remain single or attached in groups. The ovaisacteria or spherical ones are included called cocci bacteria. The following types of bacteria based on their shape under the light microscope are some bacteria have a feature to form endospores through which bacteria can survive in extreme environmental conditions Types of shapes Bacteria with different shapes exist and have different physical features in the outside world, and these features help cells cope with and adapt to external conditions. The wide diversity of shapes is defined by the bacterial cell wall and cytoskeleton. Most bacteria have a rigid cell wall that provides a definite shape to the bacteria while protecting the internal components. The high surface area-volume ratios also allow bacteria to take up all the nutrients required for survival while allowing steady growth and reproduction. Since organisms are missing in such an environment, bacteria can use accessible resources. It has been examined that the size of bacteria has an important role in the survival of organisms. However, they can be as tiny as 0.3 µmeters and as large as 0.7 µm. On average, the size of bacteria ranges from 0.5 nanometers to 0.5 µmeters. Bacteria are, in public one-tenth the size of the eukaryotic cell. The unit of measurement used in bacteriology is the micron(micrometer) which is one thousand a millimeter. What is the quantity of a bacterial cell? Change in the composition of the polymer and its consistency is credible for the various morphology and form of a bacteria cell. The bacterial cell wall is made up of peptidoglycan(murein), which is a polymer of sugars, alternating N-acetyl glucosamine (NAG) linked to N-acetylmuramic acid (NAM) and amino acids peptide chain. There are many features like motility, and mode of nutrition, that are affected by the shape of bacteria. Morphological traits of bacteria cells are an important factor in this is their adaptability and evolution. The morphology of bacteria cells not only tells the shape but also decides its pathogenicity. It is a characteristic property of a particular species. The morphology of a bacterial cell is the most distinguished property of a bacteria. that distinguished it from eukaryotes due to its difference in morphology What is the morphology of Bacterial cells?
