All about Bacteria.

Notes Bacteria be broken, single boothular telephones and are the exclusively ones characterized by prokaryotic organization. Too tiny to see with the in the raw eye, a bacterial booth is usually one of triad 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 membrane is case within a cell smother. Members of the kingdom Eubacteria give way a cell fence in made of peptidoglycan, a vane of polysaccharide molecules associate together with orbits of amino acids. somewhat eubacteria commence 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. impertinent of the cell wall and membrane, many bacteria have a gelatinous layer called a capsule. Eubacteria are assort by differences in their cell walls. A bacte rium with a cell wall containing a large hail of peptidoglycan is classified advertisement as gram-positive. A bacterium with a cell wall containing a thin layer of peptidoglycan covered by an out 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 raspy conditions much(prenominal) as drought or high temperatures. The formation of endospores in the bacterium Clostridium botulinum is respo nsible for botulism, a indisposition often! considered to be a form of food poisoning. Bacteria, which measure all eukaryotes combined, differ from eukaryotes in at least sevener important respects. 1.Internal compartmentalizationBacteria are prokaryotes and lack a cell nucleus, hostile eukaryotes. The cytoplasm of bacteria has very little internal organization. It contains no internal compartments or membrane systems. 2.Cell...
