Ndi eukaryotes zimene: tanthauzo, mbali structural

Kodi eukaryote? Yankho la funso limeneli lagona pa kapangidwe ka zinthu za mitundu yosiyanasiyana ya maselo. Mokoma bungwe lawo, ndipo ife tikuyang'ana pa m'nkhani ino.

mbali kandalama selo

Maselo a zamoyo ali m'magulu malinga ndi muyezo zosiyanasiyana. Mmodzi wa iwo - gulu la chuma cholowa ali mamolekyulu ndi DNA. Eukaryotes - zamoyo ndi, maselo amene chokongoletsedwa ngale. Izi organelle dvumembrannaya kupanga zinthu chibadwa. Mu prokaryotes, nyumba imeneyi palibe. Tizilombo timeneti ndi mitundu yonse ya tizilombo archaea.

Kapangidwe ka maselo prokaryotic

Pakalibe ngale sikutanthauza kuti zamoyo prokaryotic si nkhani cholowa. Amagwiritsidwanso ndiyotengera mu ndondomeko ya nucleotides. Komabe, uthengawu ku maselo si chokongoletsedwa pachimake ndi umaimiridwa ndi limodzi DNA zozungulira. Iwo amatchedwa pulasimidi. Chotero molekyulu ndi Ufumuyo pamwamba lamkati la Kakhungu plasma. Maselo a mtundu amagwiritsidwa mosatsata angapo organelles yeniyeni. zamoyo Prokaryotic yodziwika ndi wosazindikira, kukula yaing'ono ndi mlingo wochepa wa bungwe.

Kodi eukaryote?

Izi gulu lalikulu la zamoyo monga nthumwi ya zomera zonse, nyama ndi bowa. Mavairasi si a ma mitundu ya moyo, kotero mu gulu lino suona.

Pamwamba wagawo selo prokaryotes ankaimira plasma Kakhungu, ndipo zili mkati - cytoplasm. Izi eni theka-zamadzimadzi chilengedwe, amene amachita ntchito yothandizira, integrates onse a nyumba pamodzi. Maselo a prokaryotes amagwiritsidwa yodziwika ndi kukhalapo kwa angapo organelles yeniyeni. Izi Golgi zovuta, endoplpzmaticheskaya maukonde plastids lysosomes. Ena amakhulupirira kuti eukaryotes - zamoyo ndi maselo popanda mitochondria. Koma si choncho. Izi organelles maselo eukaryotic ndi malo mapangidwe tinthu wa ATP mphamvu chonyamulira mchipindamo.

Eukaryotes: zamoyo Zitsanzo

Eukaryotes ndi atatu maufumu a chilengedwe. Komabe, ngakhale kufanana maselo awo pali kusiyana kwambiri. Mwachitsanzo, mbewu yodziwika ndi okhala organelles apadera chloroplasts. Ndi mu zovuta ndondomeko photochemical zimachitika akatembenuka inorganics kwa shuga ndi oxygen. Animal maselo nyumba amenewa mulibe. Iwo amatha kuyamwa zakudya okha wokonzeka. Kusiyana pakati pa kapangidwe ndi kapangidwe ka zida pamwamba. Maselo nyama pa Kakhungu plasma ndi glycocalyx. Ndi viscous pamwamba wosanjikiza sosotoyaschy mapulotini, lipids ndi chakudya. Zomera, yodziwika ndi khoma selo. Malowa ali pamtunda pa plasma Kakhungu. Selo khoma ndi chimafotokozera zovuta chakudya mapadi ndi pectin, amene anawupereka iwo mphamvu ndi chinthu chimodzimodzi.

Kodi eukaryotes, woimiridwa ndi gulu la bowa? Maselo a zamoyo zodabwitsa izi kuphatikiza mbali structural zomera ndi nyama. Kapangidwe ka maselo linga lawo chakudya ndi mapadi ndi chitin. Komabe, iwo mulibe chloroplasts tsitoplpzma Choncho, ngati maselo nyama, amatha okha kupereka heterotrophic njira.

MwaukadauloZida mbali ya kapangidwe ka eukaryotes

Chifukwa eukaryotes zonse zamoyo kuti utakwaniritsa mpweya wambiri wa chitukuko ndi Zafalikira dziko? Choyamba, chifukwa cha mkulu mlingo wa specialization wa organelles awo. Mphete molekuda DNA ali maselo mabakiteriya amapereka Chophweka njira la kubalana awo - selo magawano pakati. Chifukwa cha ndondomeko ici ulikubala enieni buku majini maselo mwana. Kubalana wa mtundu uwu Ndithu zipangitsa kupitiriza kwa mibadwo ndi kupereka mokwanira kudya kubwezeretsa maselo oterowo. Komabe, maonekedwe a zilembo latsopano magawano ziwiri, ndipo mawu sindingakhoze kupita. Izi zikutanthauza kuti atengere zinthu kusintha, zamoyo izi sindingathe. Maselo eukaryotic khalidwe la ndondomeko ya kugonana. Patapita ake, pali nzeru zambiri majini ndi recombination ake. Chifukwa cha zimenezi, anthu onse amabadwa ndi watsopano, zizindikiro zambiri zothandiza, amene anakonza genotype awo ndipo akhoza opatsirana ku mibadwomibadwo. Ichi ndi chiwonetsero cha kusintha chibadwa, ndilo maziko a kusanduka.

Choncho, m'nkhani ino ife anayang'ana pa zimene eukaryotes. Mfundo imeneyi chamoyo amene maselo muli phata. Gulu la zinthu monga oimira onse zomera ndi nyama, komanso bowa. Phata ndi dongosolo selo okhazikika amene amathandiza kusunga ndi kulanda zinthu majini informitsii ndiyotengera mu nyukiliotayidi ndondomeko ya mamolekyulu DNA.
