Chii eukaryotes: tsananguro, STRUCTURAL zvinhu

Chii chinonzi eukaryote? Mhinduro yomubvunzo uyu iri nemamiriro zviri nemarudzi akasiyana-siyana emasero. The nuances Sangano ravo, uye tinotarisa munyaya ino.

Structural zviri muchitokisi

Masero zvipenyu dzinoiswa maererano siyana zvinodiwa. Mumwe wavo - sangano nhaka zvinhu huri DNA mamorekuru. Eukaryotes - zvinenge zviri, mumasero riri wakashongedzwa tsanga. Izvi dvumembrannaya organelle dzine magene zvinhu. In prokaryotes, mamiriro ichi vasipo. Utachiona ava ose utachiona uye archaea.

The mamiriro masero prokaryotic

Pasina tsanga hazvirevi kuti prokaryotic zvinenge haisi nhaka zvinhu. Chinonziwo encoded ari kutevedzana kwezviitiko nucleotides. Zvisinei, majini ruzivo hauna wakashongedzwa chinoumba uye hunomiririrwa chete dzeraundi morekuru reDNA. Zvakanyorwa kunzi plasmid. morekuru kwakadaro wanamatira romukati pose plasma membrane. Masero iyi mhando vari kunyimwa zvinoverengeka chaiwo organelles. Prokaryotic zvinenge dzinoratidzwa chinyakare, duku kukura uye pasi pamwero sangano.

Chii chinonzi eukaryote?

Izvi guru boka zvipenyu zvinosanganisira vamiririri miti yose, mhuka uye hunokuvadza. Nemavhairasi vari non-cellular zvipenyu, saka ari kupatsanura ichi havana vaiona.

The pemvura chikwata Sero prokaryotes aimiririra plasma Kamudzira, uye munyika zviri - cytoplasm. Ichi chinhu zvemukati Semi-mvura ezvinhu, iyo anoita nokutsigira basa, integrates vose hurongwa pamwe. Nokuti masero prokaryotes vanoitwa dzinoratidzwa kuvapo zvinoverengeka chaiwo organelles. Golgi ino yakaoma, endoplpzmaticheskaya zvakarukwa plastids lysosomes. Vamwe vanodavira kuti eukaryotes - zvinenge zviri masero kushayiwa mitochondria. Asi hazvina kudaro. organelles izvi mumasero eukaryotic ndivo nzvimbo inotungamirwa mamorekuru ose ATP keriya simba muchitokisi.

Eukaryotes: zvinenge mienzaniso

Eukaryotes vari vatatu umambo zvakasikwa. Zvisinei, pasinei yokufanana mumasero dzavo pane Misiyano. Somuenzaniso, chirimwa dzinoratidzwa tune specialized organelles chloroplasts. Zviri izvi kunzwisisa photochemical muitiro rikauya rokutendeutsa Inorganics kuti shuga uye oxygen. Animal masero Zvivako vakadaro havana. Vanokwanisa kupinza vakagadzirira chete muviri. Kusiyana pakati marongerwo sechivako pemvura midziyo. In masero mhuka plasma Kamudzira ndiye glycocalyx. Zviri viscous pamusoro rukoko sosotoyaschy kwemapurotini, lipids uye makabhohaidhiretsi. Zvinomera, dzinoratidzwa muchitokisi parusvingo. It iri plasma membrane. Sero rusvingo kunorondedzerwa zvakaoma makabhohaidhiretsi cellulose uye pectin, izvo kuzvipa simba uye Rigidity.

Ndezvipi eukaryotes, uko kunomiririrwa boka notumwe? Masero aya zvinenge zvinoshamisa sangana STRUCTURAL zvinhu zvose zvinomera uye mhuka. Mamiriro avo muchitokisi rusvingo makabhohaidhiretsi vari cellulose uye chitin. Zvisinei, havasi saka ane chloroplasts tsitoplpzma, sezvinoita masero mhuka, inokwanisa chete kupa heterotrophic nzira.

Advanced zviri sechivako eukaryotes

Nei eukaryotes vose zvipenyu hwapedza dzakakwirira siyana okukura uye vakapararira mhiri nyika? Chokutanga, nemhaka kudunhu padanho specialization ose organelles dzavo. Ring molekuda DNA huri mumasero mabhakitiriya, anopa nyore nzira yavo kubereka - sero nekupesana nepakati. Somugumisiro izvi pave chaiwo nemagene kopi mwanasikana masero. Kubereka kwakadai zvechokwadi kunovimbisa ari chamazuva zvizvarwa uye kupa zvakakwana zvakasimba playback masero dzakadaro. Zvisinei, chimiro vatambi vatsva weboka nepakati, uye kutaura hazvigoni kufamba. Izvi zvinoreva kuti kuchinja kuchinja mamiriro, zvinenge izvi asingagoni. For eukaryotic Masero yo zvounzenza muitiro. In vadzore, pane kupanana magene mashoko yayo recombination. Somugumisiro, vanhu vanoberekwa vaine itsva, kazhinji kubatsira zviratidzo, izvo wakaiswa pakati genotype dzavo uye zvinogona kutapukira kubva kumarudzi namarudzi. Izvi zvinoratidza nemagene kushanduka, inova hwaro shanduka.

Saka, munyaya ino isu akatarira chii eukaryotes. Pfungwa iyi ndiyo muviri ane masero ane neerekitironi. Ichi boka zvipenyu zvinosanganisira vamiriri zvose zvinomera uye mhuka upenyu, uyewo notumwe. Chinoumba chinhu zvachose sero mamiriro izvo chinopa okuchengetera uye kuchinjwa magene informitsii zvipenyu encoded ari nucleotide kutevedzana kwezviitiko DNA mamorekuru.
