All about Bacteria.

Notes Bacteria be broken, single mobile phoneular telephones and are the that ones characterized by prokaryotic organization. Too tiny to see with the sensitive eye, a bacterial cell is usually one of trey 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 groyne made of peptidoglycan, a vane of polysaccharide molecules link up together with mountain chains of amino acids. somewhat eubacteria get down 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. orthogonal of the cell wall and membrane, many bacteria have a gelatinous layer called a capsule. Eubacteria are separate by differences in their cell walls. A bacterium with a cell wall containing a large hail of peptidoglycan is separate as gram-positive. A bacterium with a cell wall containing a thin layer of peptidoglycan covered by an outmost 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 coarse conditions much(prenominal) as drought or high temperatures. The formation of endospores in the bacterium Clostridium botulinum is responsible for botulism, a unhealthiness often considered to be a form of food poi soning. Bacteria, which marrow all eukaryo! tes combined, differ from eukaryotes in at least septenary important respects. 1.Internal compartmentalizationBacteria are prokaryotes and lack a cell nucleus, different eukaryotes. The cytoplasm of bacteria has very little internal organization. It contains no internal compartments or membrane systems. 2.Cell...
