All about Bacteria.

Notes Bacteria be broken, single carrelular telephones and are the all ones characterized by prokaryotic organization. Too tiny to see with the defenceless eye, a bacterial jail cell is usually one of ternion 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 bulwark made of peptidoglycan, a vane of polysaccharide molecules united together with cooking stoves of amino acids. somewhat eubacteria go 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. distant 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 categorise 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 rough conditions much(prenominal) as drought or high temperatures. The formation of endospores in the bacterium Clostridium botulinum is responsible for botulis m, a unhealthiness often considered to be ! a form of food poisoning. Bacteria, which make sense all eukaryotes combined, differ from eukaryotes in at least seven important respects. 1.Internal compartmentalizationBacteria are prokaryotes and lack a cell nucleus, contrary eukaryotes. The cytoplasm of bacteria has very little internal organization. It contains no internal compartments or membrane systems. 2.Cell...
