Cyst - oluthile eziphilayo. Imisebenzi kunye neentlobo

Mhlawumbi, kwindalo akukho ngakumbi survivable kwaye malilungiselelwe kokusingqongileyo eziphilayo ngaphezu iintsholongwane apho. Ezi fom ubomi kwiseli ekwaziyo withstanding iinguqu ezinkulu kwamaqondo obushushu, uxinzelelo kunye iasidi. Bathi ke imbalela ixesha elide kungekho manzi, naphezu nasisihlo yeemeko elilungileyo yokusingqongileyo kwakhona ukuba abuyele ubomi obuqhelekileyo. Njengoko lentsholongwane ingaphila apho babulala ezinye izinto eziphilayo?

Yintoni a cyst eziphilayo

Le ntsholongwane ziyakwazi ukuba basinde iimeko ezingalunganga usebenzisa encystment. Undoqo yale nkqubo kukuba iiseli iintsholongwane engqongwe iqokobhe zamafu. Enyanisweni, lo ngowona isizathu sokuba magciwane ningoyiki wembalela okanye utshintsho lobushushu.

Cyst - luhlobo lwe ubukho amagciwane ngazo ukuba bakwazi ukuphila phantsi kweempembelelo izinto ezingalunganga. Esi sakhiwo zokhuselo eyakuthi ekuso hayi kuphela eziphilayo prokaryotic, kodwa ezinye protists.

Iimpawu iiseli quiescent

Cyst - oku luhlobo oluthile kakhulu iintsholongwane, nto leyo ekhokelela kwezinye utshintshwano ngaphakathi kwi seli. Ezi fitsha ixhomekeke kuhlobo encystment, kodwa kukho ezinye iimpawu ngokubanzi yenkqubo. Okokuqala, iseli kwenziwa balo; lwajikeleza ngeenxa iqokobhe olusisiqulatho, nto leyo umqobo kwizinto engentle yokusingqongileyo.

Kodwa encystation ngokupheleleyo okanye ngokuyinxenye ukuvala iiseli unxibelelwano kokusingqongileyo, ngoko magciwane kufuneka silungiselele ukuyilwa kwiqokobhe ashinyeneyo. iintsholongwane Okokuqala mazingagcini essentials neziyobisi kunye nee-enzayim, nto leyo eya kusebenza nkqu encystment. Emva koko, iseli ulahlekelwa ezinye isakhiwo yayo, ukuze ususe engeyomfuneko okwethutyana kwi iindleko zamandla mzuzu.

Cyst - le yenye amanqanaba lomjikelo wobomi ezincinane ezininzi. Ngenxa yoko, inkqubo encystment kuba ngamaxesha athile. Ezinye cysts ingaqhubeka iphila emva kweminyaka emi-5 okanye eli-10. Kukho ubungqina bokuba cysts of lenyama ungaphila ukuya kwiminyaka eli-16. Inika ilungelo ukubiza izinto ezininzi ziphila njengoko kakhulu kwiplanethi yethu.

Iimeko ezinegalelo encystation

ISifundo iintsholongwane kwiimeko zaselebhu lubonise ukuba isixhobo kakhulu iba neemeko egwenxa cyst. Ukuzimisela kweeseli encysted kwi izitya petri phantsi kwempembelelo yeemeko ezahlukeneyo kubonisa ukubaluleka lexinene udonga cell. Zeziphi izizathu ezibangela ukuyilwa cysts?

1. Utshintsho ku lobushushu.

2. Guqula kwi xi lezinyibilikisi ngaphakathi eliphakathi.

3. Vaporization wamanzi (amanzi dehumidification).

4. Ukungabikho okanye ezingaphezu kwe-oksijini.

5. Ukungabikho kwezixhobo ukutya.

Ingongoma wokugqibela ebangela encystment iintsholongwane. Ukuba petri yokutyala thanga iintsholongwane, ukutya ekupheleni kwimpahla uninzi iiseli imali eluhlobo cysts. Ukuba medium osisityebi izondlo, yindlela encystment kuncinane.

Amanye amaqela eziphilayo cyst iintlobo phantsi kweemeko ezahlukileyo. Umzekelo, ciliates, le nkqubo kuyimfuneko rearrangements isixhobo senyukliya ngaphakathi kwiseli. Encystation iiseli olwaye lwamfimfitha eukaryotic kwenzeka ukuze uphume phakathi komkhosi, size ke sisifikele bume ephilileyo akafanelekanga. Ezinye abameli prokaryotes kunye eukaryotes basebenzisa cysts yokuvelisa kwakhona.

iintlobo encystment

Iinjongo apho kudlula kwala magciwane ukuya cyst isigaba? Nazi iindidi ezimbalwa encystment, apho zifumaneka kakhulu kwindalo.

1. cysts kokuphumla.

Ezi iintlobo iintsholongwane kunye protists ukuba yayifuzisela encystment, apho iseli luhlangabezana iimeko engentle yokusingqongileyo.

2. cysts Veliswa.

Olu hlobo uphawu ngenxa abameli ezininzi ciliates. Kulo mzekelo, cysts ukwenza inwebu ngokwaneleyo zingcakacile, iseli iqala bababele ngokuphindaphindiweyo. Ngenxa yoko, le Ungqabhuko cyst nokukhanya uyacima inani elikhulu iikopi kumzimba koomama.

3. cyst kokudla.

kweendlela iiseli ezinqabileyo uhlobo ezimbalwa ezincinane. Apha cyst - sisixhobo ukugaywa olusebenzayo. Olu hlobo encystment uphawu eziphilayo, amarhamncwa, emva 'ukutya' nexhoba zenza isikhumba yaye ekuqaleni ukugaya ixhoba.
