Prokaryotic Sero - sero muviri kwerubwinyo rwakagara rwuripo yenyukireya

Prokaryotic sero - iri, chokwadi, chete akaronga muviri, izvo anoramba unhu madzitateguru. Ivo zvakanyatsorongwa dzinounzwa kupatsanura umambo Monera, izvo zvinosanganisira utachiona uye cyanobacteria (zvitema-rwegirini algae).

Chii saka "nyore" iri maumbirwo pre-zvenyukireya zvinenge? Sero Prokaryotic haina neerekitironi, takapoteredzwa ravo goko, mitochondria uye plastids. Pakati chinhu cytoplasm nucleoid (nucleotide), iyo ine chimwe nukleproteidnoy mamiriro dzine annular morekuru reDNA. kunzwisisa uku kunonzi kwemabhakitiriya chromosome. Munotapira muchitokisi utachiona uye zvitema-nyoro algae anosiiwa ari kwokunze svikiro guru sero rusvingo kana Kamudzira uye mucous membrane. Rusvingo zvokutanga STRUCTURAL hadzisisina ainyanya rinoumbwa imwe pfuma murein (yakaumbwa kwemapurotini uye makabhohaidhiretsi), izvo anoita mashandiro panze marangwanda, achipa chimiro uye nokudzivirira masero kubva zviwane. Yomukati Kamudzira ane zvinotevera kushanda: kudzivirirwa, zvokufambisa, uye unonyatsoruramisa omumwe kuitika.

The womukati maumbirwo masero prokaryotic anoratidza kuti cytoplasm wayo sezvamunoita ndehwokutamburira zvikuru kupfuura yenyukireya (eukaryotic). Rine ribosomes, izvo zvinodiwa mapuroteni usage. Uyewo pane Kamudzira mamiriro, izvo kuita zvisipo organelles - mitochondria, endoplasmic reticulum, Golgi uye plastids. Somuenzaniso, sero prokaryotic ane bulging diaphragm, unonzi mesosoma. Zviri pano kuti nedanho afemeruke uye simba pakabudiswa utachiona.

Uyewo, pre-zvenyukireya zvinenge vanokwanisa sporulation, asi havazivi inoberekesa navo. The spores kana cysts vari gobvu membranes kuti vabatsire utachiona kurarama vanoshorwa ezvinhu kwavari. Kutsigira upenyu mune asiri chinoumba mamiriro anogona kuchengeta zvinokurisa - mafuta, dzakaoma makabhohaidhiretsi.

Sero prokaryotic anogona kuwanda nokuda kupesana, yotunga uye conjugation. rutoto nzira kunobva mhando utachiona kana cyanobacteria. Division uye yotunga - nzira kuti kubvumira tichishandisa nokukurumidza kuwedzera kwevanhu saizi. Conjugation kunoitika muna E. coli, pabonde chichiitwa, izvo zvinoita kuti majini kusiyana tusingaoneki.

Saka, prokaryotes - a masero pre-zvenyukireya, izvo regai kunge formalized muchitokisi musimboti uye vari kunyimwa zhinji Kamudzira organelles, asi anogona kuchinja. Kuti vakakwanisa kuchinja kurarama mumamiriro ezvinhu apo hapana chinopukunyuka zvakawanda - munhu reactor yenyukireya, matsime mafuta. A kuwanda vamiririri umambo Monera vari pathogenic uye zvinogona kukonzera zvakasiyana-siyana zvirwere muvanhu, mhuka uye zvinomera (nemanyoka, tonsillitis, tiibhii). Uyewo, vamwe tusingaoneki hunodyidzana nemimwe eukaryotes (symbiogenesis), semuenzaniso senitrogen kutara mudzi nodule utachiona kuti nyuchi pamusoro midzi bhinzi.
