Eukaryotic muchitokisi chacho STRUCTURAL uye dzichipfekeka sangano

eukaryotic Sero dzidzo aiva wechipiri kukosha (pashure nechitarisiko upenyu pachahwo) chiitiko shanduka. Huru uye dzinokosha musiyano pakati eukaryotes kubva prokaryotes ndiyo pamberi kupfuura wakakwana gadziriro yacho genome. Nemhaka chidzoke uye kukura foni neerekitironi, rinooneka zvakawedzera mwero anochinjika pamusoro unicellular zvipenyu kuti kugara kuchinja mamiriro ezvinhu uye kukwanisa kuchinja nokukurumidza pasina kuita chero nouchapupu kushanduka nhaka magene hurongwa.

Eukaryotic muchitokisi, iro cytoplasm izvo inyaya vanoshingaira metabolic urongwa, akaparadzaniswa zvakanaka kubva kuchengetera nzvimbo, iyo Verenga uye kuberekana yokugara mashoko, akakwanisa mberi chaivo shanduka. Ichi chikomo uye inokosha shanduka chiitiko, maererano masayendisiti, kwete zvazoitika azvarwa pane mabhiriyoni 2,6 akapfuura, panguva mharadzano vaviri Geological varipo -. Archean uye Proterozoic.

Urefu adjustability uye kugadzikana zvoutachiona hurongwa chinhu chinodiwa kuti uzere chaivo-shanduka. Zviri kwavo kukwanisa marefu kwadzakabva eukaryotic sero aigona ichishanduka kupinda zvipuka zvine masero akawanda zvinenge vane kunzwisisa STRUCTURAL sangano. Zvechokwadi, muna zvipuka zvine masero akawanda utachiona gadziriro, masero pamwe chete genome, achichinja kuita kuchinja mamiriro, kuumba yakasiyana zvachose, zvose wavo morphological zvivako, uye functionality, micheka. Ndizvo kukunda mukuru Kushanduka eukaryotes, izvo zvakakonzera chidzoke zvakadaro hombe siyana muupenyu siyana panyika uye mbudo kuti shanduka nhandare wemunhu pachake.

The mamiriro masero ane eukaryotic mhando ane wandei nemamwe zvinhu dzisiri noruzhinji prokaryotes. Sero Eukaryotic rine yakawanda magene zvinhu (90%), iyo kusimbiswa chromosomal zvivako kuti kunovimbisa Kusiyanisa kwavo uye specialization. Chero eukaryotic Sero dzinoratidzwa yoga core. Ndiro huru runoratidza ichi mhando nemasero. Chimwe musiyano unokosha kubva prokaryotes vari organelles masero eukaryotic - zvakasiyana zvachose uye intracellular ezvirevo.

Sero Eukaryotic, achienzaniswa prokaryotic ane kunzwisisa multistage hurongwa maonero akasiyana siyana zvinhu. Zvakasikwa kune zvinowanzoitika yezvisikwa eukaryotic muchitokisi mhando. Vose vari inozivikanwa rinoshamisa siyana kuti imhaka kunyatsoreva kudiwa-shanduka kwadzakabva. A chinokosha zvikuru chinoratidza eukaryotes ndiko yavo yokusafa compartmentalisation - localization vose nokukanganisika pezvakaitwa mune munhu cellular nezvikamu, akaparadzaniswa nevanhu intracellular membrane. Eukaryotes Vakawanda kunzwisisa STRUCTURAL zvinoriumba. Dzakadai Kamudzira hurongwa; cytoplasmic chizvaro, inova huru intracellular fuma; cellular organelles - huru dzichipfekeka zvinoumba eukaryotes.
