A mafi yawa wakilan unicellular kwayoyin - kwayoyin da archaea. A cikin tambaya na inda suke zaune, amsar mai sauki: ko'ina! Muhimmanci ga wadannan kwayoyin zuwa matsakaici (ko - substrate) ya dace da rayuwa ba. Kuma mafi muhimmanci - gaban isasshen danshi, ruwa da samuwa.

A yanayi a cikin ƙasa, a cikin ruwa, a cikin wasu kwayoyin. Ka yi la'akari da cikakken bayani.

A cikin ƙasa

Idan muka magana game da jama'a muhallin sanaki guda-celled, kasar gona sun dauke mafi girma adadin. A humus, chernozem da kuma sauran kasa da cewa su ne m substrate, akwai mafi kyau duka domin da harshen damo: gina jiki, da wani adadin na ruwa. Akwai kuma wani hasken rana kai tsaye, amma dadi zazzabi, wanda damar guda-celled bunƙasa da kuma ninka. Yawancin wadannan kwayoyin yi a canza aiki matattu kwayoyin, su bazuwar cikin ta bijiro da batun kafa sassa - da abubuwan da alama mahadi. Saprophagous (abin da ake kira kwayoyin da cewa ciyar a kan saura) suna da hannu a cikin samuwar wani m humus. Duk da haka, a cikin m kwayoyin da pathogens ne ba. Alal misali, jamiái tetanus da botulism, wanda za a iya samu a cikin jikin mutum don daban-daban fata raunin.

A cikin ruwa

Da yake jawabi na jama'a muhallin sanaki guda-celled kwayoyin cuta, ba a ma maganar cikin sararin ruwa rufe mafi yawan yankin na duniya duniya. Ga su an wanke daga ƙasa, yafi. Saboda haka, a cikin ruwa, musamman a tsaye, kazalika a cikin ƙasa, yana iya zama miliyoyin kwayoyin cuta ( 'yan grams na ruwa). Community ne cikakken kuma ba tare da qeta unicellular. Daga cikin su - da causative jamiái na typhoid, dysentery, cutar kwalara da sauran tsanani cututtuka da mutane.

A cikin iska

Ga unicellular wakilan ba haka ba ne da yawa, amma shi ne quite isa. An sani cewa da yawa cututtuka canjawa wuri yafi by Airborne droplets. A iska, wadannan unicellular fall da ake wãtsarwa da micro-saukad da na ruwa tanã fita iska igiyoyin. Masana kimiyya sun gano cewa kwayoyin cuta na iya "isa karkata" a irin wannan hanya zuwa iyakar cikin yanayin duniya. Bad wasu unicellular da kuma jin a vacuo, forming wani gwangwani lifeforms - spores.

A fata da kuma cikin mu

Wani jama'a muhallin sanaki guda-celled kwayoyin? A taro na kwayoyin ne a kan 'yan Adam fata, a wasu daga ta yankunan: armpits, crotch, mucous membranes. Ciki da talakawan dan kasa "na zaune" game da uku kilo na live nauyi kwayoyin. A babbar rundunar kwayoyin (a gwada yawa sharuddan - biliyoyin), wanda ba za a iya watsi da. Wannan shi ne yafi sada makwabta, forming microflora da lafiya mutum. Amma akwai kuma wasu pathogens cewa zai iya sa babban lahani, kuma a karkashin wani yanayi.
