Eukaryotes - ndi zamoyo amene maselo ndi phata

Eukaryotes - kwambiri mwapang'onopang'ono anakonza zamoyo. M'nkhaniyi tiona mmodzi wa akuluakulu a zinyama limabweretsa gulu ili ndi zimene mbali asiya gulu kutenga nawo udindo lalikulu mu dziko organic.

Kodi eukaryotes

Malinga ndi tanthauzo la zosiyana, eukaryotes - ndi zamoyo amene maselo muli phata chokongoletsedwa. Zikuphatikizapo maufumu zotsatirazi: zomera, nyama, bowa. Ndipo ziribe kanthu momwe zovuta thupi lawo zoti. The tosaoneka amoeba, Volvox madera, chimphona sequoia - eukaryotes onse.

Ngakhale maselo amenewa nthawi zina zimakhala akhoza mosatsata phata. Mwachitsanzo, si mu maselo ofiira. M'malo mwake, ili maselo a magazi lili hemoglobin kunyamula mpweya ndi mpweya. Maselo amenewa ali ndi phata yekha mu magawo oyambirira a chitukuko. Ndiye, organelle uyu awonongedwa, ndi izo, ndi kutaya luso kugawanitsa dongosolo lonse. Choncho, mwa kuchita ntchito zake, maselo amenewa amafa.

Kapangidwe ka eukaryotic

Mu maselo a eukaryotes ndi phata. Ndipo nthawizina ngakhale mmodzi. Izi organelle dvumembrannaya lili masanjidwewo ake mfundo majini ndiyotengera mu DNA. Phata tichipeza unit pamwamba, amene amathandiza zoyendera zinthu, ndi masanjidwewo - wa zachilengedwe mkati. Ntchito yaikulu ya nyumba imeneyi - kusunga mfundo majini ndi kutengerapo ake maselo mwana wamkazi chifukwa magawano.

Mumtima pakati sing'anga ndi zigawo angapo. Choyamba izo karyoplasm. Lili nucleoli ndi chromatin chingwe. Yotsirizira zigwirizana mapulotini zidulo mkati. Inakhalapo pamene DNA helix. Iwo basi onyamula mudziwe chibadwa. Eukaryotes - ndi zamoyo zimene mitundu iwiri ya mitima ungadzakhazikitsidwe zina: vegetative ndi zobereka. A chitsanzo chapadera cha ichi - ciliate. Zake zobereka pakati zolimbitsa kuteteza ndi kufala kwa genotype, ndi vegetative - lamulo la mapuloteni biosynthesis.

Kusiyana waukulu sanakwiye ndi eukaryotes

Prokaryotes mwapereka phata. Gulu la zinthu ndi woona yekha ufumu wa chilengedwe - Mabakiteriya. Koma ngati mbali structural sizikutanthauza kuti maselo a zamoyo izi palibe onyamula mudziwe chibadwa. Mabakiteriya akupanga zozungulira molekyulu ya DNA - pulasimidi. Komabe, iwo imakonzedwa mu mawonekedwe a masango mu malo ena cytoplasm ndipo alibe envelopu wamba. Chotero eg amatchedwa nucleoid. Pali kusiyana wina. DNA maselo prokaryotic si zogwirizana ndi mapuloteni pachimake. Asayansi anakhazikitsa kuli plasmids ku maselo a eukaryotes. Iwo ali mu ena theka-yoyenda yokha organelles, monga mitochondria ndi plastids.

Progressive mbali structural

Eukaryotes ndi zamoyo zimene zimakambidwa zovuta kwambiri dongosolo pa magulu osiyanasiyana a bungwe. Choyamba zonse lokhudza njira patsogolo. mabakiteriya Nucleoid amapereka chophweka kwa iwo - pa nsoka wa khungu mu awiri. Eukaryotes - zamoyo zomwe angathe ndi mitundu yonse ya kubereka ya mtundu wawo: kugonana ndi asexual, parthenogenesis, conjugation. Iwo amapereka kufotokoza mfundo chibadwa, zikamera ndi kuphatikiza mu genotype wa zingapo zochititsa zothandiza, choncho ndi anatengera bwino nthawi yosintha zinthu zachilengedwe. Mbali imeneyi ndi eukaryotes analola kuti zatenga malo lalikulu mu dongosolo organic dziko.

Choncho eukaryotes ndi zamoyo amene maselo ndi phata chokongoletsedwa. Zikuphatikizapo zomera, nyama ndi bowa. Kupezeka kwa pakati bokosi pang'onopang'ono kwa nyumbayi, kupereka mkulu mlingo wa chitukuko ndi anatengera.
