Cell Eukaryotic iyo ururka dhismaha iyo functional

waxbarashada cell eukaryotic wuxuu ahaa kan labaad ee muhiimadda ay leedahay (ka dib muuqaalka kore ee nolosha laf ahaanteed) dhacdo evolutionary. Farqiga ugu muhiimsan ee saldhigga u ah eukaryotes ka prokaryotes waa joogitaanka nidaam ka kaamilsan ee hiddawadayaasha ah. Thanks to soo bixitaanka iyo horumarinta ee bu'da unugga ah, xadaa degree of waafajinta of noolaha unicellular in shuruudaha si joogto ah la beddelo oo awood u leh inay si deg deg ah ula qabsan iyadoon la sameyn wax isbeddel la taaban karo nidaamka hidaha ee la iska dhaxlo.

Eukaryotic cell, cytoplasm ka mid ah taas oo meel ka mid ah geeddi socodka dheefshiidka firfircoon, iyo sidoo kale laga soocay deegaanka kaydinta, ka akhrin iyo taranka macluumaad hidde, wuxuu ahaa awoodaan in ay sii horumar nafleyda. Tani waa durkin iyo dhacdo evolutionary muhiim, sida ay saynisyahano, ugu dambayn 2.6 billion sano ka hor ma ka dhacay, isgoyska laba durkiya dhulka -. Archean iyo Proterozoic.

adjustability Dhererka iyo xasiloonida ee dhismayaasha noolaha waxay shardi u tahay horumar nafleyda buuxa. Waa awoodda sare loogu talaggalay cell eukaryotic xuubsiiban karo noolaha multicellular ururka dhismaha adag. Indeed, in multicellular hababka noolaha, unugyada la hiddawadayaasha la mid ah, qabsashadoodu xaaladaha beddelo, foomka aad u kala duwan, labadaba guryaha ay morphological, iyo ka shaqeynayaan ah, dhar. Taasi waa guul weyn oo horumar ah eukaryotes, taasoo keentay in soo bixitaanka of sida kala duwan weyn ee noocyada nolosha on the planet iyo ka bixitaanka in saaxadda evolutionary isaga qudhiisu nin.

Dhismaha unugyada of nooc eukaryotic ayaa dhowr Tilmaamo gaar ah oo aan prokaryotes sifo. cell Eukaryotic ku jira xaddi badan oo ah wax hidde (90%), taas oo ku urursan dhismeedka koromosoomyada in ay hubisaa in ay ku kaladuwan yihiin iyo takhasuska. cell eukaryotic kasta oo lagu gartaa asaasiga ah gaar ah. Tani waa feature ugu muhiimsan ee lagu garan noocan ah unugyada. Arin kale oo muhiim ah ka prokaryotes waa organelles unugyada eukaryotic - noocyo kala duwan oo dhismeedka adkaysiga joogtada ah iyo intracellular.

cell Eukaryotic, iyadoo marka la barbar dhigo prokaryotic leedahay nidaam adag multistage aragtida of walxaha kala duwan. In dabiiciga ah waxaa ka mid ah nooca caadiga ah gacanta eukaryotic universal. Oo kulligoodna waxaa lagu gartaa kala duwanaanta cajiib ah taasina waxaa ugu wacan in si hufan baahida loo qabo qalab evolutionary. A muujinta aad u muhiim ah oo eukaryotes waa compartmentalisation soo jireenka ah - deegaamaynta dhammaan geedi socodka lagmamaarmaanna u ah ee compartments gacanta shakhsi, kala xuub intracellular. Eukaryotes leeyihiin qaybaha dhismaha badan oo adag. Sida nidaamka xuub; Matrix cytoplasmic, oo waa hubaasha weyn ee intracellular; organelles gacanta - qaybaha ugu muhiimsan ee functional of eukaryotes.
