All about Bacteria.

Notes Bacteria be broken, single kioskular phoneular telephones and are the altogether ones characterized by prokaryotic organization. Too tiny to see with the tender eye, a bacterial cell is usually one of tierce basic shapes; bacillus, a rod shaped cell; coccus, a spherical cell; or spirillum, a spiral cell. A few kinds of bacteria aggregate into stalked structures or filaments. A bacterias plasma tissue layer is case within a cell smother. Members of the kingdom Eubacteria give way a cell border made of peptidoglycan, a vane of polysaccharide molecules connect together with ranges of amino acids. somewhat eubacteria go through a cell wall cover with an out membrane layer made of large molecules called lipopolysaccharides. A lipopolysaccharide is a chain of sugar molecules with a lipid wedded to one end. alfresco of the cell wall and membrane, many bacteria have a gelatinous layer called a capsule. Eubacteria are classified ad ad by differences in their cell wa lls. A bacterium with a cell wall containing a large hail of peptidoglycan is classified as gram-positive. A bacterium with a cell wall containing a thin layer of peptidoglycan covered by an outer(a) membrane is classified as gram-negative. These terms refer to a bacteriums reaction to a staining procedure developed by the Danish microbiologist Hans Gram.

Some bacteria form thick-walled endospores around their chromosomes and a small bit of cytoplasm when they are exposed to rough conditions much(prenominal) as drought or high temperatures. The formation of endospores in the bacterium Clostridium botulinum is resp onsible for botulism, a distemper often co! nsidered to be a form of food poisoning. Bacteria, which tot all eukaryotes combined, differ from eukaryotes in at least septenary important respects. 1.Internal compartmentalizationBacteria are prokaryotes and lack a cell nucleus, conflicting eukaryotes. The cytoplasm of bacteria has very little internal organization. It contains no internal compartments or membrane systems. 2.Cell...
