Uyini morphology microorganism?

I morphology kwala magciwane - isayensi kwakuphathelene ukutadisha isimo sabo, isakhiwo, izindlela zokukhiqiza kabusha kanye nokunyakaza.

Kubaluleka nokuthola

Lokhu isayensi ngempela okukhulu iye ukutadisha nezindaba eziningi. Naphezu kweqiniso lokuthi wonke amagciwane ayibonakali iso womuntu, nxa kuyikuthi ikhona futhi kukhona kokubili "elihle" umzimba kanye ezimbi.

Amagciwane ingatholakala zonke izindawo ukubonakaliswa zokuphila: amanzi, inhlabathi, umoya, futhi ezinye izinto eziphilayo.

Uqala ukufunda ngethemba amagciwane Leeuwenhoek usosayensi odumile wahlanganyela emsebenzini wokukhiqiza lens lokuqala, ukuvumela izinto ukwandisa kuze kube izikhathi ezingaphezu kwamakhulu amabili. Yabona wamangala ngokuphelele. Usosayensi wathola ukuthi amagciwane abanga zikhona yonke indawo futhi zonke sihluke nomunye. Ngakho, Leeuwenhoek kwaba owathola nezilwanyana ezincane.

ULouis Pasteur waqala ukufunda lo mbuzo, njengoba morphology microorganism, futhi wathola ukuthi akukhona nje ukuthi ama isakhiwo ezahlukene wamakhasi nokuma kwawo, kodwa futhi izindlela ezahlukene kanye nokunyakaza nasekuvezeni izithombo zaso ezintsha. Wathola ukuthi ezinye izilokazane ezincane ziyingozi umzimba womuntu, futhi abanye, kunalokho, eziwusizo. Wabuye wathola ukuthi amagciwane abanga ezifana imvubelo, kungaholela ukuvutshelwa izinqubo.

I morphology eziphilayo avunyelwe ososayensi abaningi baziqambela wokugoma ezahlukene kokusisiza ukuba sibhekane nesimo ne izifo human obulalayo.

ngezigaba

Nezilwanyana ezincane ezibhekwa abameleli eziphilayo kulencane kule mbulunga enguMhlaba. Ngokuvamile, zingabantu unicellular, futhi ababheke kuphela ngesibonakhulu esinamandla kakhulu.

Le ndlela usayizi ukuphila ulinganiswa micrometer futhi nanometer. Emvelweni, bafumana omningi, ngakho banesikhathi kokungafani okukhulu e isakhiwo, indlela ikhona futhi ukunyakaza.

Ngokusho omisiwe ngezigaba, ama-bacterium zihlukaniswe acellular, unicellular futhi amaningi. Ngesikhathi esifanayo bahlukene ngezigaba ezifana: isikhunta, nembiliso, phages, lamagciwane.

Okuncane amagciwane

Esifundweni ngezihloko ezifana morphology microorganism, ukunakwa okukhulu kufanele zikhokhelwe amagciwane. Ngokuvamile, zingabantu eziphilayo owumphumela (nakuba zikhona ezehlukile) futhi abe impela awalingani ngobukhulu. Ezinye zazo yilezi micrometer 500.

Kunezinhlobo eziningana zama-bacterium kuhluke ifomu yabo. Lokhu kungabandakanya induku emise, ibhola-okwenyanga nezinto eziphilayo crimped. Ake sicabangele kohlobo ngalunye.

amagciwane eyisiyingi kwezokwelapha abizwa ngokuthi "cocci". Ngokuvamile benjalo round ukuma, nakuba ngezinye izikhathi kukhona okusaqanda, angenziwa emabhontjisi emise. Abakwazi akhiwe hhayi kuphela ngamunye kodwa ngababili, ngesimo amaketanga noma imivini.

Abaningi babo babe nomthelela ongemuhle umzimba womuntu. Ngokwesibonelo, streptococci kubangele komzimba, futhi staphylococci banesibopho kumiswa ubovu nezinqubo ukuvuvukala.

izinti bacterium emise, yiwona ovame kakhulu. Lawa nezilwanyana ezincane eziholela sofuba, i-typhoid fever, uhudo.

Ezinye izinhlobo izinduku ngaphansi kwezimo ezimbi kwemvelo, yakha ezinhlamvu. amagciwane anjalo ngokuthi imbewu eletha.

Spore ukwakheka - inqubo ezithakazelisa kakhulu futhi kuyinkimbinkimbi, ngoba cell ngokwayo yalolu hlobo ihluke kakhulu kusukela bacilli abavamile. agumenti Inkonde ngayinye ifakwe umshini ulwelwesi aminyene futhi okuqinile, kuyilapho amanani azinakwa yamanzi. Lokhu cell ayidingi umsoco, kokuba uyeke ukuhambisa, futhi zizalane. Kulesi zengxabano kungase kube esiphuthumayo sokuba izimo ekuphileni, njengomshado okushisa kakhulu eliphezulu kakhulu noma eliphansi. Kepha njengoba masinyane njengoba kuza kubo indawo evumayo, masinyane baqala izimpilo zabo.

amagciwane Twisted zivame kakhulu otholakala uhlobo ukhefana noma curls. Ngokuvamile, alawa magciwane abangela izifo ezifana ugcunsula kanye nekholera.

amagciwane Abaningi bayakwazi ukuhambahamba, futhi benza kanjalo ngosizo flagella tabobunjwa futhi ubude.

Amagciwane ande sokuhlukanisa. Le nqubo kuyashesha kakhulu (njalo ngemva kwemizuzu engu nanhlanu kuya kwangamashumi amabili). ayanda kakhulu kungabonwa ukudla futhi endaweni ehlukile, esesikhundleni esiphakeme a umsoco.

amagciwane

Amagciwane akunakubangelwa iqembu ethile eziphilayo musa babe isakhiwo yeselula. Lezi izinto eziphilayo mancane kakhulu, ngakho kungabonwa kuphela ngesibonakhulu electron. Ezinye izinhlobo amagciwane ungenziwa kuphela aqukethe amaprotheni acid nucleic.

Wonke umuntu okungenani kanye empilweni yakhe bebhekene izifo ezibangwa alawa magciwane. Lezi zihlanganisa umkhuhlane, isifo sokusha kwesibindi, isimungumungwane kanye nezinye izifo eziningi.

amakhowe

Leli qembu microorganism ubalulekile futhi. Amakhowe akudingeki chlorophyll e ukwakheka, futhi akusho ukukhiqiza zamagama izinto eziningi eziphilayo. Badinga imikhiqizo ukudla ngomumo eyenziwe. Yingakho isikhunta ngokuvamile zingatholakala ku nenhlabathi evundile noma kwimikhiqizo ukudla.

Mushroom libhekene izindlela ezahlukene zizalela. Lezi zihlanganisa hhayi indlela kuphela ngokobulili futhi asexual, kodwa futhi vegetatively.

imvubelo

Isibiliso kukhona eziphilayo owumphumela fixed, kokuba ifomu onhlobonhlobo. Kukhona zombili round nezinhlobo okusaqanda, nenduku isikela.

Lolu hlobo nezilwanyana ezincane kuthiwa esakazwa. Bona ingatholakala kwi izitshalo enhlabathini, kanye nokudla, okuyinto ke buba bubi nakakhulu. Ezinye zazo bayakwazi ukuguqula ushukela ku-carbon dioxide futhi utshwala. Le nqubo ibizwa ngokuthi lwezithelo olubangela ukubila. He is bayindlala kakhulu embonini yezokudla.

Morphology of nezilwanyana ezincane: amagciwane

Kuyaphawuleka ukuthi leli gciwane - uhlobo ukuphila kwavela eplanethini yethu ngqa. sici ngokuyinhloko isakhiwo cell. Ngokungafani eukaryotes (anama core), prokaryotes (amagciwane) zingenalo nuclei.

Lezi nezilwanyana ezincane zitholakala kuzo zonke izizinda zokuphila kanye nethonya eliqondile ukuphila komuntu ngezinga elikhulu kanye.

Ososayensi uhlukanise amagciwane futhi isimiso Umbuso indawo. Kukhona zinhlobo kuwusizo futhi kuyingozi. Ngilusizo abahilelekile ye-photosynthesis, nethonya elihle ku-womuntu wokugaya ukudla uhlelo, futhi ngokuvamile sisetshenziswa umkhakha.

Ukutadisha nezilwanyana ezincane morphology inikeza umqondo jikelele khona kwabo, futhi ubanika ithuba lokufunda ngezinzuzo futhi efanele ibe kuhlu lokuhlukumezeka ezimweni ezihlukahlukene.

amaseli Standard webhaktheriya sakhiwa ncenye:

• Ulwelwesi plasma. Lokhu cell isici akuyona sihluke ulwelwesi of eukaryotes.

• Mesosoma - isakhi ekhethekile ngawo kungenzeka ukunamathisela iseli impahla sitholwa njengefa.

• Nucleotide. Akusona ikhenela athuthukiswe ngokuphelele. Iqukethe zonke-chromosome.

• Ribosomes - organelles ethize, kuthatha cishe amane amaphesenti isikhala yeselula.

Ngaphandle izici ezingenhla, ingxenye amaseli prokaryotic sihlanganisa: udonga capsule namaseli lwamafinyila ukumboza. amagciwane amaningi ayakwazi ukuthuthela ngokuzimela futhi ninamathele ebusweni. Lokhu bakwenza ngokusebenzisa flagella akhethekile villi.

I morphology microorganism microbiology amagciwane, isikhunta nembiliso

Virus - umzimba ezikhethekile, okuyinto ayinakho isakhiwo yeselula. kuyizinhlayiyana ngasinye siqukethe egobolondweni, kanye etholakala maphakathi ulwazi umongo.

Kodwa isakhiwo amaseli isikhunta kunzima ngaphezu kokwanoma namanye amagciwane. Ukwakheka sihlanganisa cell yabo nucleus futhi vacuoles. Ngokusho isakhiwo, zifana kakhulu isitshalo, kodwa abe ukuma ezahlukene. Kubonakala sengathi isikhathi eside, sesigcilikisha ekhelini ngokuthi hyphae. Ngokuvamile hyphae enjalo yakha ama-mycelium.

Imvubelo amaseli akhiwa kuzo zonke izingxenye eukaryotes, kodwa ngaphandle kwalokho, izingxenye esingokwemvelo nezinye. ulimi lwawo luhluke itholakala lokuthi ukuthi they fanele linganayo izimfanelo kokubili izilwane nezitshalo.

umzimba

Morphology futhi physiology nezilwanyana ezincane ivumela ukuqonda izigaba oyinhloko ekuphileni kwabo. Kamuva amagciwane ngendlela efanayo njengoba yinkimbinkimbi ukuphila, ukuhlanganiswa kwezici lipids, amafutha kanye carbohydrate. Kodwa ngaleso izinqubo ezifanayo ezitokisini zabo zihlukile.

Izazi ziye zakhomba ezimbili izinhlobo eukaryotes: autotrophs futhi heterotrophs.

Uhlobo lokuqala uyakwazi synthesize izinto eziphilayo ukusuka compounds wezinto ezingaphili, kodwa kuveza ukuguqulwa izinqubo izingxenye organic yesibili.

Ngokuvamile heterotrophs kukhona nezilwanyana ezincane yisinanakazana. Zidla kuphela ngezithukuthuku izakhi engena emzimbeni womkhosi wawo.

Kukhona futhi saprophytes. Basuke bondliwa eziphilayo efile kwemiqondo izinto.

morphology isakhi izilokazane ezincane - sekuyinto kuyingxenye ebalulekile ukufunda ngokuphila amagciwane. Nokho, ngaphezu isakhiwo cell futhi kufanele bacabangele izinhlobo umzimba. uhlobo Constructive iye okuxoxwe ngawo ngenhla. Kukhona ukushintshana amandla.

Izazi ziye zakhomba zalezi zinhlobo amandla:

• Photosynthesis. Le nqubo kungenziwa kwenziwe khona komoya-mpilo, futhi ngaphandle kwalo.

• Lwezithelo olubangela ukubila. Cishe le ndlela yokusabela amandla kwenzeka ngenxa ukwehlukana molecule wali band acid udluliselwa Adp.

• Breathing. Nezilwanyana ezincane uphefumule hhayi kuphela ngenxa umoya-mpilo, kodwa futhi ne organic compounds nokumbiwa.

Ukudluliswa ukwaziswa kwezakhi zofuzo

Kunezindlela eziningana ukuze uthumele ukwaziswa kwezakhi zofuzo prokaryotes (morphology futhi taxonomy microorganism nazo ezichazwe kulesi sihloko). Ake sicabangele ngokuningiliziwe ngamunye wabo:

• Conjugation - indlela yokudlulisa ulwazi zofuzo komunye umzimba kwenye kuphela contact abo ngqo;

• Uguquko - ukudluliswa uhlobo, lapho abanikeli wabelana ngolwazi abamukeli;

• Transduction - indlela yokudlulisa ngqo ka lezinceku impahla usebenzisa phages.

Izindlela cwaningo microorganism morphology

zisebenzisa izindlela ezinjalo isifundo inembe kakhulu kunazo zonke isakhiwo prokaryotes njengoba microscopy futhi staining.

izindlela ezincane sokutadisha nezilwanyana ezincane morphology ekhiqizwa ngenxa electron futhi ukukhanya microscopes. Ochwepheshe baye basungula izindlela eziningana ukuze bathole imiphumela olunembile kakhulu.

Morphological indlela ukutadisha kusenza microscope ukuze kubuyekezwe uhlaka sezitokisi, kanye ukuhamba alo futhi ikhono nokuzala.

indlela bokuphila evumela ukuba sicabangele ukusabela izilokazane ezincane ezintweni ezihlukahlukene, kanye nekhono ukuzivumelanisa nezimo ezihlukahlukene.

Nge indlela isiko kungaba kwenziwe ucwaningo we silwanyana e konemimoya izakhi. Le nqubo ivumela ukuhlonza umthamo ekukhuleni nasekuvezeni izithombo zaso ezintsha.

Morphology of nezilwanyana ezincane (i-microbiology) - lena isayensi kubaluleke kakhulu ukuthi study bacterium nezinye owumphumela. Ungacabangi ukuthi amagciwane kuphela ezibangela umonakalo emvelweni bese umzimba womuntu. Awa, akusinjalo. Ngaphandle kwawo, ukuphila Emhlabeni ngeke kwenzeke.
