Zvakasikwa, ichi rikaitika kubereka yemiti uye chimwe celled mhuka.

Asexual kubereka ezvinhu zvipenyu

Simple nokupesana kuchengetwa unicellular zvinomera nemhuka, dzakadai ciliates, amoebae, uye vamwe algae. Chokutanga, muchitokisi musimboti yakakamurwa mitosis nepakati, uye ipapo constriction aumbwa, uye mubereki chiratidzazvizhinji iri muzvikamu zviviri kuti muri vana zvipenyu.

In asexual kubereka mhuka akapona chete mune dzimwe nzira: sechipanji, coelenterates, flatworms, tunicates. Izvi zvitsva mumwe zvinenge yaunganidzwa yotunga kana fission, uye ipapo kuparadzana mubereki muviri mugove kuchipedzisa pamberi yose. Mune zvimwe zviitiko, kukwanisa kuva munhu muviri kwemhuka vane dzomuviri. Complete hydra Somuenzaniso, unogona kuva kubva maviri ramazana rutivi. Kana asexual kubereka achangogadzwa akasika specimens zvinobva kuna masero akawanda kuburikidza nomunhu kana mitotic mapoka kupa mashoko chete kuvabereki, iyo nhaka sero mubereki muviri.

Asexual kubereka zvinomera

Kwakapararira nzira iyi kubereka iri chirimwa umambo. Pane zvinhu zvinoverengeka zvinomera zviri zvakanaka inoparadzirwa tubers, layering, cheka, uye kunyange mashizha zvinogona kushandiswa pave zvinenge itsva vegetative nhengo yacho nomubereki chirimwa. Izvi rworudzi asexual kubereka inonzi vegetative, uye tinoberekwa chaizvo akaronga zvinomera. Muenzaniso kubereka kwakadaro kunogona kunzi ndebvu akadaro kunoitika Somuenzaniso, Strawberry.

Sporulation - asexual kubereka, kunoitika muna miti yakawanda, yakadai algae, ferns, mosses, notumwe vamwe zvokukura kukura.

Mangoti pane mamiriro ezvinhu akanaka, spores inoparusa goko, sero anotanga kugovera kakawanda, achipa upenyu nomuviri mutsva.

Yotunga ndiyo nzira kubereka nomubereki kana chiratidzazvizhinji anosiiwa chiduku nzvimbo muviri iyo gare gare anoumba mwana muviri.

A seti vanhu vari zvizvarwa kubva kuzitateguru achibatsirwa kwakadai kubereka mu zvipenyu vanonzi miitiro inoburitsa zvinhu zvakanyatsofanana.

Asexual kubereka zvinowanzodavirwa kushandiswa mune zvokurima kubudisa zvinomera aine unhu zvinobatsira upenyu hwevanhu. "Ndebvu" Long, mabukira vakawarira mastrawberry, michero makwenzi uye miti - cheka. Masayendisiti achiongorora zvigadziriswe wokuberekana, kudzidza kuongorora uye kushandisa kukura kwavo. Cell tsika vaida pakutanga magene ruzivo inoparadzirwa uye ipapo kukura kubva kwavari dzaida muti wose.
