Prokaryotic seleng e - seleng e phelang pele ho ntoa ea nyutlelie

Prokaryotic seleng e - e le hantle, feela lokisetsa 'mele, eo e lule e mekhoa ea balimo. Ba hlophisehileng abetsweng arola 'muso Monera, e kenyeletsang libaktheria le cyanobacteria (putsoa-tala dimelametsing).

Se e le "e bonolo" ka sebōpeho sa lintho tse phelang pele ea nyutlelie? Prokaryotic seleng e se nang motheo, pota-potiloe ke khetla ea bona, mitochondria le plastids. Bohareng ke cytoplasm nucleoid (nucleotide), e leng e na le sebopeho mong nukleproteidnoy se se akaretsang annular DNA molek'hule. rarahaneng ena o bitsoa chromosome baktheria. Fetisisang libaktheria seleng e le 'mala o moputsoa-tala dimelametsing e aroloa ho ea Link mahareng le letšo-letšo leboteng seleng e kapa komiki le lera mucous. Lerako la tsa motheo mehaho unit trust e haholo-holo a qapa ea ntho murein (thehoa liprotheine le lik'habohaedreite), e leng etsa ho sebetsa ha masapo ka ntle, a le fa sebopeho le ho sireletsa liseleng tse tsoang ho susumetsa ba bang ka ntle. The lera ka hare o na le mesebetsi e latelang: tšireletso, lipalangoang, le ho arola temoho ea susumetsa ba bang.

Mohaho ka hare ea lisele prokaryotic fana ka maikutlo a hore cytoplasm le sebopeho lona e futsanehileng haholo ho feta hore ba libetsa tsa nyutlelie (eukaryotic). E na le ribosomes, tse hlokahalang bakeng sa tswakana protheine. Hape ho na le lera sebopeho, e sebetsa e le organelles le sieo - mitochondria, endoplasmic reticulum, Golgi le plastids. Ka mohlala, li-cell prokaryotic na le diaphragm bulging, eo e bitsoa mesosoma. Ke mona moo tshebetso ya respiration le matla a ho lokolloa ka libaktheria.

Hape, tse phelang pele ea nyutlelie ba ka khona ho sporulation, empa ha ba bakang le bona. The hlobo kapa cysts tse teteaneng lera la hore thusa libaktheria ho pholoha maemo a sa thabiseng bakeng sa bona. Ho boloka bophelo ka maemo a batho bao e seng mantlha ba khona ho boloka limatlafatsi - mafura, e rarahaneng lik'habohaedreite.

Sele prokaryotic ka ata ka karohano, megagametophyte le conjugation. ikatisa mokhoa itšetlehile ka mofuta oa libaktheria kapa cyanobacteria. Karohano le budding - mekhoa e lumella batlang e le ka potlako eketsa boholo baahi. Conjugation eo o hlahellang teng E. coli, tshebetso ho kopanela liphate, tseo ho tlatsetsa ho phetoho liphatseng tsa lefutso ka microorganisms.

Kahoo, prokaryotes - ka lisele tse ea pele ho ea nyutlelie, tseo se li wa semmuso sele khubu 'me li amohuoa organelles ngata lera, empa le matla a ho fetola. Hore ba ne ba khona ho tloaela ho phela tikolohong e moo ha ho motho pholohang ho feta - ka melena nyutlelie, liliba oli. A palo e khōlō ea baemeli ba 'muso Monera ke pathogenic le ka etsa hore mefuta e fapaneng ya le mafu ho batho, liphoofolo le limela (letšollo, tonsillitis, lefuba). Hape, ba bang ba microorganisms lula symbiosis le eukaryotes (symbiogenesis), mohlala naetrojene lokisa sepeiti libaktheria motso likotoloana hore kolone ea ka metso ea legumes.
