Pūtau Eukaryotic me tona whakahaere hanganga me te mahi

mātauranga pūtau eukaryotic ko te tuarua i roto i te faufaa (i muri i te ahua o te ora iho) he hui whanaketanga. Ko te rerekētanga matua, me te tumu o eukaryotes i prokaryotes ko te aroaro o te pūnaha atu tino o te huinga ira. Ngā mihi ki te putanga me te whanaketanga o te karihi pūtau, koi nui haere tohu o urutau o ngā rauropi ki te tikanga te huri wā me te kaha ki te urutau hohoro kahore hanga tetahi huringa nui ki te pūnaha ira tuku.

Eukaryotic pūtau, te cytoplasm o e ko te wāhi o ngā tukanga pūkoro tinana kaha, pai wehea i te rohe rokiroki, te pānui, me te tāruarua o te mōhiohio ā-ira, i taea ki te atu kukuwhatanga koiora. Ko te rohe, me te kaupapa whanaketanga hira tenei, kia rite ki kaipūtaiao, kihai puta i muri atu i te 2.6 piriona tau ki muri, i te pūtahitanga o rua tohu whenua arowhenua -. Archean me Proterozoic.

Teitei adjustability me te pūmautanga o ngā hanganga koiora ko te tikanga matua mō te kukuwhatanga koiora tonu. Ko to ratou aravihi teitei mō te urutaunga pūtau eukaryotic taea whanake ki kaiao multicellular ki whakahaere hanganga matatini. Oia mau, i roto i te multicellular pūnaha koiora, ngā pūtau ki te genome taua, ka huri ki ngā āhuatanga rerekē haere, te hanga i te tino rerekē, e rua i roto i o ratou āhuatanga morphological, me te taumahinga, papanga. te wikitoria nui o te kukuwhatanga o eukaryotes, kua arahina nei ki te putanga o te taua momo nui o puka ora i runga i te ao me te putanga ki te ao whanaketanga o te tangata ia e he.

Ko te hanganga o ngā pūtau o te momo eukaryotic He maha ngā āhuatanga ahurei e kore e prokaryotes āhuatanga e. Kei pūtau Eukaryotic te nui nui o te rauemi ira (90%), hāngai nei i roto i ngā hanganga pūira e whakarite to ratou pārōnaki me te ite taa'e. Tetahi pūtau eukaryotic āhuatanga e te matua motuhake. Ko te āhuatanga motuhake matua o tenei momo o ngā pūtau tenei. Ko tētahi atu rerekētanga nui i prokaryotes he organelles o ngā pūtau eukaryotic - he momo o ngā hanganga pūmau, me te intracellular.

pūtau Eukaryotic, whakaritea ki prokaryotic he pūnaha multistage matatini o perception o ngā matū. I roto i te natura i reira e etahi momo pūtau eukaryotic te ao angamaheni. Kua āhuatanga katoa o ratou i te kanorau whakaponohia e he tika ïa ki te hiahia mo te urutaunga whanaketanga. He āhuatanga tino nui o eukaryotes ko ratou compartmentalisation tūturu - localization o tukanga matüora katoa i roto i compartments pūtau takitahi, wehea e te membrane intracellular. Eukaryotes i maha wāhanga hanganga matatini. Ko te hunga i te pūnaha membrane; kopu cytoplasmic, i te mea te taonga intracellular matua; organelles pūtau - te wāhanga mahi matua o eukaryotes.
