Asexual kubereka, mbali yake ndi mawonekedwe

Asexual kubalana - ndi kubalana wa chamoyo imene palibe nawo anthu ena ndi kusewera mtundu wawo amapezeka ndi kulekanitsa imodzi kapena maselo angapo kuchokera chamoyo akuchikazi. Mu ndondomeko otere nawo kokha munthu kholo. The mitotic chifukwa kwathunthu kutsatira foni mayi wapachiyambi.

Asexual kubalana ndi losavuta kwambiri. Ichi ndi chifukwa chakuti kapangidwe gulu la majeremusi zokhala ndi selo imodzi ndi osavuta. Zamoyo mu mode ili la kubalana kubereka okha mofulumira kwambiri. M'mikhalidwe yabwino, ola lililonse nambala ya maselo amenewa ndi kawiri. Ntchito imeneyi mpaka kalekale, mpaka padzakhala kusintha mwachisawawa mu malamulo chibadwa, otchedwa kusintha.

Mu chikhalidwe, izi zimachitika mu kubalana zomera ndi nyama zokhala ndi selo imodzi.

Asexual kubalana wa zamoyo

Zambiri magawano anamuona pa zomera unicellular ndi nyama monga ciliates, amoebae, ndi ena algae. Choyamba, phata selo lagawidwa ndi mitosis mu theka, ndiyeno constriction ndi aumbike, ndi kholo chitsanzo lagawidwa pawiri kuti tiri ana a zamoyo.

Mu asexual kubalana nyama anapulumuka yekha m'njira: thonje, coelenterates, flatworms, tunicates. Awa latsopano zamoyo munthu akamagwira budding kapena fission, kenako kupatutsa kholo thupi gawo kukhala anamaliza pamaso lonse. Nthawi zina, kuthekera kukhala mu chamoyo munthu nyama ndi ziwalo. Complete hydra Mwachitsanzo, angathe kuchokera awiri magawo zana. Pamene asexual kubereka kumene analenga toyesa ochokera ku maselo angapo umodzi kapena mitotic magulu kupereka majini mfundo zofanana, amene adzalandira selo kholo lake.

Asexual kubalana zomera

Ponseponse motere la kubereka mu ufumu mbewu. Pali zomera kuti bwino zimafalitsidwa ndi tubers, layering, cuttings, ndipo ngakhale masamba amene angagwiritsidwe ntchito kubala zamoyo latsopano ziwalo vegetative wa mbewu kholo. Mtundu wa asexual kubalana amatchedwa vegetative, ndipo chibadidwe ndi zomera mwadongosolo. Chitsanzo cha kubereka akhoza ankaona ndevu ngati amene amapezeka Mwachitsanzo, sitiroberi.

Sporulation - asexual kubereka, amene amapezeka mu zomera zambiri, monga algae, Mumapezekanso, ndere, bowa pa ena magawo chitukuko. Mu nkhani iyi, kafalitsidwe limagwirira maselo wapadera zedi, nthawi zambiri ataphimbidwa ndi chipolopolo wandiweyani, amene amateteza iwo Mavuto a chilengedwe: kutentha, kuzizira, youma. Mwamsanga pamene pali zinthu zabwino, spores Kasupe chipolopolo, selo imayamba kugawanitsa mobwerezabwereza, kupereka moyo ndi thupi latsopano.

Ikuphukira pali njira kubalana ndi kholo pamene chitsanzo ndi wosiyana ndi malo ochepa a thupi ku chomwe pambuyo ndipamene thupi mwana.

Zogwiritsira anthu amene anachokera kwa kholo limodzi ndi thandizo la mtundu wa kubalana mu zamoyo amatchedwa oyeserera.

Asexual kubalana chimagwiritsidwa ntchito ulimi kubala zomera ndi ya makhalidwe amene ali othandiza pa moyo wa munthu. Long "ndevu", mphukira kufalitsa strawberries, tchire zipatso ndi mitengo - cuttings. Asayansi akufufuza njira la kubalana, kuphunzira mmene liyang'anire ndi kusamalira chitukuko. Cell zikhalidwe anakhumba mudziwe majini poyamba zimafalitsidwa kenako kukula mwa anayenera chomera lonse.
