Iseli Eukaryotic nentlangano zayo zokusebenza kwaye esebenza

imfundo iseli eukaryotic yaba yeyesibini ukubaluleka (emva kokuvela nobomi) isiganeko yokuzivelela. Umahluko ophambili lusisisekelo eukaryotes ukusuka prokaryotes kuba phambi kwenkqubo ngokhona kucokisekileyo zofuzo. Ngenxa ukuvela kunye nophuhliso inucleus yeseli, okwanda iqondo bhetyebhetye of kwiseli neemeko ukutshintsha rhoqo kwaye ukukwazi ukuziqhelanisa ngokukhawuleza ngaphandle kokwenza naluphi na utshintsho kakhulu kwinkqubo yemfuza ilifa.

Eukaryotic iseli, ukuba kukho icytoplasm yazo ummandla iinkqubo esebenzayo pathways, ezahlulwe kakuhle ukusuka kwindawo yokugcina, read kunye phindana ulwazi yemfuza, wakwazi phambili kwemvelo. Le elilwela kunye isiganeko obalulekileyo yendaleko, ngokutsho izazinzulu, hayi kwenzeka emva kweminyaka-2.6 billion eyadlulayo, ekuhlanganeni kweendlela kwemihlaba ezimbini zejoloji -. Archean kunye Proterozoic.

Height nokulungiseka kunye nozinzo kwezinto eziphilayo yinto yokuqala efunekayo ukuze ngendaleko ngokupheleleyo eziphilayo. Kuyinto umthamo wabo omkhulu yokulungisa iseli eukaryotic ukuba zisiba eziphilayo multicellular nentlangano entsonkothileyo zesakhiwo. Eneneni, xa multicellular ngokweenkqubo zebhayoloji, iiseli kunye ufuzo efanayo, wamkela iimeko ukutshintsha, ibe eyahlukileyo ngokupheleleyo, kokubini ngeempawu zazo morphological, kunye nokusebenza, amalaphu aqhelekileyo. Oko ke olu uloyiso olukhulu izinto zazivelela of eukaryotes, nto leyo eye yakhokelela ekubeni ukuvela ezahlukeneyo elikhulu enjalo iintlobo ukuphila emhlabeni kunye uphume enkundleni yendaleko umntu ngokwakhe.

Ubume zeeseli luhlobo eukaryotic inemisebenzi ezizodwa ezininzi engeyiyo yona prokaryotes isici. yeseli Eukaryotic iqulethe isixa esikhulu genetic material (90%), nto leyo buzinze izakhiwo chromosomal eqinisekisa ukuba iyantlukwano yabo lokufunda izifundo ezikhethiweyo. Nayiphi iseli eukaryotic iphawulwa engundoqo eyahlukileyo. Le ke inkalo ephambili olwahlula olu hlobo iiseli. Omnye umahluko ebalulekileyo ukusuka prokaryotes ezi organelles leeseli eukaryotic - ezahlukeneyo izakhiwo ezisisigxina intracellular.

iseli Eukaryotic, xa kuthelekiswa ne prokaryotic inenkqubo entsonkothileyo multistage okuqonda kwezinto ezahlukeneyo. Kwindalo kukho ezinye jikelele uhlobo eukaryotic. Bonke bephela luphawulwa ezahlukahlukeneyo Amazing kungenxa kanye imfuneko yokuba lithathelwe yokuzivelela. Into ebaluleke kakhulu eukaryotes yi nangodidi okusegazini - kwasendaweni zonke iinkqubo kwemichiza siyinxalenye yezinye ngamnye cellular, ezahlulwe ndizayo intracellular. Eukaryotes kuba namacandelo amaninzi entsonkothileyo zesakhiwo. Ezifana nenkqubo ndizayo; matrix cytoplasmic, nto leyo ke into ephambili intracellular; organelles cellular - iinkalo eziphambili esebenzayo eukaryotes.
