mesosome (ˈmɛsəˌsəʊm) n (Biology) any of various membranous structures found in some bacterial cells, now thought to be a result of techniques used in preparing cells for microscopymes•o•some (ˈmɛz əˌsoʊm, ˈmɛs-, ˈmi zə-, -sə-)
n. 1. the anterior portion of the abdomen in arachnids. 2. a whorled structure in bacteria, extending inward from the cell membrane and containing respiratory enzymes. [1955–60] mesosomeenUK
mesosome[′mez·ə‚sōm] (microbiology) An extension of the cell membrane within a bacterial cell; possibly involved in cross-wall formation, cell division, and the attachment of daughter chromosomes following deoxyribonucleic acid replication. mesosomeenUK
mesosome [mes´o-sōm] an invagination of the bacterial cell membrane. Various mesosomes are associated with DNA replication, cell secretion, and electron transport.mes·o·some (mes'ō-som), A convoluted membranous body formed by involution of the plasma membranes of certain bacteria; it functions in cellular respiration and septum formation. [meso + G. soma, body] mesosome The name given to folded invaginations of the plasma membrane of bacteria, caused by fixation prior to examining them by electron microscopy; now of historic interest only.mes·o·some (mez'ō-som) A convoluted membranous body formed by involution of the plasma membranes of certain bacteria; functions in cellular respiration and septum formation. [meso + G. soma, body]mesosome a structure formed in the cell membrane of bacteria by invagination. |
