Eukaryotic selo ndi chipembedzo chake structural ndi zinchito

eukaryotic maphunziro selo anali wachiwiri kufunika (pambuyo maonekedwe a moyo) chochitika chisinthiko. Chachikulu kusiyana ndi chachikulu eukaryotes ku prokaryotes ndi pamaso pa dongosolo chonse cha matupi athu ndi. Chifukwa cha zikamera ndi kukula kwa munthu phata selo, zikuchepa kuchuluka digiri ya kusinthasintha kwa zinthu unicellular kuti zinthu zonse kusintha ndi luso atengere mofulumira popanda kusintha kulikonse yokulirapo dongosolo cholowa chibadwa.

Eukaryotic selo cytoplasm amene ndi mbali njira kagayidwe kachakudya yogwira bwino anasiyanitsidwa ndi malo osungirako, anawerenga ndi kugawanika kwa uthengawu ku maselo ankatha kupititsa patsogolo kusanduka kwachilengedwenso. Ichi ndi chikhomo ndi yofunika chisinthiko chochitika, malinga ndi asayansi, inachitika pasanafike zaka mabiliyoni 2.6 zapitazo, pa mphambano ya zikhomo ziwiri Geological -. Archean ndi Proterozoic.

Msinkhu adjustability ndi mtendere wa nyumba kwachilengedwenso ndi choyambilira mfundo zonse kwachilengedwenso. Ndi maluso kwambiri anatengera eukaryotic selo akhoza kusintha mu zamoyo multicellular ndi zovuta structural bungwe. Ndithudi, multicellular machitidwe zamoyo maselo ndi matupi chomwecho, kusinthasintha kwa zinthu kusintha, kupanga chosiyana, onse katundu wawo morphological, ndi magwiridwe, nsalu. Kuti ndi chigonjetso chachikulu cha zamoyo wa eukaryotes, zomwe zachititsa kuti zikamera umenewu yaikulu zosiyanasiyana zamoyo padziko lapansili ndi potulukira m'bwalolo zinachokera munthuyo.

Kapangidwe ka maselo a mtundu eukaryotic lili ndi zinthu zingapo wapadera omwe si khalidwe prokaryotes. Eukaryotic selo lili wambirimbiri zinthu majini (90%), amene anaikira mu nyumba chromosomal kuti zipangitsa zosiyanasiyana awo ndi specialization. Aliyense selo eukaryotic yodziwika ndi pakati osiyana. Ichi ndi zazikulu zimasiyanitsa mbali ya mtundu wa maselo. Kusiyana kwina kofunika kwa prokaryotes ndi organelles maselo eukaryotic - zosiyanasiyana nyumba okhazikika ndi okhudza maselo ambiri.

Eukaryotic selo, poyerekeza ndi prokaryotic ali ndi zovuta multistage dongosolo la kuzindikira zinthu zosiyanasiyana. Mu chikhalidwe pali ena mmene chilengedwe eukaryotic mtundu selo. Onse yodziwika ndi kuchuluka zosaneneka kuti ndi chifukwa enieni kufunika anatengera chisinthiko. Mbali yofunika kwambiri eukaryotes n'chobadwa compartmentalisation awo - kutanthauzira njira zonse amuzolengedwa mu zipinda ma payekha, wosiyana ndi Kakhungu okhudza maselo ambiri. Eukaryotes ambiri zovuta zigawo structural. Monga dongosolo nembanemba; cytoplasmic masanjidwewo, umene uli waukulu okhudza maselo ambiri mankhwala; ma organelles - waukulu zinchito zigawo za eukaryotes.
