Cell Prokaryotic - shaqeeyo cell pre-nuclear

cell Prokaryotic - waa, in fact, kaliya diyaarin jidhka, kaas oo xajisto ka midtahay awowayaashood. Waxay si nidaamsan loo qoondeeyey kala boqortooyada Monera, taas oo ka mid ah bakteeriyada iyo cyanobacteria (algae buluug-cagaaran).

Waa maxay sidaa "fudud" ee qaab dhismeedka of noolaha pre-nuclear? cell Prokaryotic ayaa xuduntii lahayn, hareereysan ay qolof u gaar ah, mitochondria iyo plastids. In badhtamaha uu ka yahay nucleoid cytoplasm ah (nucleotide), oo ka kooban hal-dhismeedka nukleproteidnoy kooban annular Britain DNA. adag Tan waxaa lagu magacaabaa koromosoomyada ah bakteeriyada. Ubadatay bakteeriyada cell iyo algae buluug-cagaaran laga soocay dibadda dhexdhexaad ah cufan derbiga cell ama kaabsal iyo xuub-axaleedka. derbigii unit dhismaha hoose waxaa inta badan ka kooban murein ah walax (sameeyay borotiinada iyo carbohydrates), taas oo qabata shaqo ee lafaha dibadda, siinta qaabka iyo ilaalinta unugyada ka meersan dibadda. xuub hoose ayaa hawlahan: ilaalinta, gaadiidka, iyo qaybintii aragtida ah ku meersan.

Qaab-dhismeedka gudaha unugyada prokaryotic soo jeedisay in cytoplasm iyo inta ay ka kooban yahay wax badan ka miskiinsan yahay in nuclear ah (eukaryotic). Waxaa ku jira ribosomes, taas oo lagama maarmaan u ah Avv borotiinka. Sidoo kale waxaa jira qaab-dhismeedka xuub, taas oo u dhaqmaan sida organelles maqan - mitochondria, reticulum endoplasmic, Golgi iyo plastids ah. Tusaale ahaan, unugyada prokaryotic ayaa diaphragm a ferjiga, oo la yidhaahdo mesosoma. Waxaa halkan waa in habka of Neefta iyo tamarta sii daayo in bakteeriyada.

Sidoo kale, noolaha pre-nuclear awood u sporulation, laakiinse iyagu ma ay nooc iyaga la. The kudka ama fiix waa xuubka cufan oo kaa caawin bakteeriyada si ay u noolaadaan xaaladaha allifey oo iyaga u. In la joogteeyo nolosha ee xaaladaha aan muhiimka ah ay awoodaan in ay ku kaydiso nafaqo - dufanka, carbohydrates adag.

unugyada prokaryotic dhufan karaa by qeybinta, gaysashada iyo conjugation. Habka taranta ku xiran tahay nooca bakteeriyada ama cyanobacteria. Division iyo ka gaysashada - Hababka u oggolaan xad si deg deg ah loo kordhiyo baaxadda dadweynaha. Conjugation taas oo dhacda in E. coli, habka galmada, kaas oo ku kordhinaya kala duwanaanshaha hidaha ee sheyga.

Sayidka, prokaryotes - a unugyada pre-nuclear, taasoo aadan ayaa rasmi bu'da unugga iyo waxey la'yihiin organelles badan xuub, laakiin awood u leh inay beddesho. nuclear-ka nuclear, ceelasha saliidda - in ay awoodaan in ay la qabsadaan si ku nool deegaan ay ka mid ma soo waaqsado ka badan ahaayeen. Tiro badan oo wakiillo ka socda boqortooyada Monera waa pathogenic iyo waxay keeni kartaa noocyo kala duwan oo cudurro qabtay oo ah dadka, xoolaha iyo dhirta (dabadhiig, qumanka, qaaxada). Sidoo kale, qaar ka mid ah sheyga ku nool khaasatan la eukaryotes (symbiogenesis), tus qamaar nitrogen bakteeriyada xidid nodule in gumeysato on xididdada digiraha.
