Chii asexual kubereka inonzi mhuka uye zvinomera

Kubereka ezvinhu zvipenyu - a kubereka vana dzokubereka vanhu vakaita pachavo, pamwe kutora chikamu dzepabonde masero vacho vose, saka riri kuonekwa zvepabonde nokugara default. Iyi tsika kuchiitwa zvose upenyu Panyika. With ichi zvose pachena. Zvino ngationei chii chinonzi asexual kubereka, uye nzira iyo zvinoitika.

Chii chinonzi asexual kubereka

Asati mukuronga pfungwa iyi, tinoona kuti chimiro chezvinhu asexual kubereka mune zvose zvipuka zvine masero akawanda uye unicellular zvinenge. Vasina chiratidzo, tsanangura kuti kune wekutanga ndiwo zvinomera uye hunokuvadza, uye kune wechipiri - nyore zvipenyu (akadai amoeba). Zita nzira iyi kubereka anotaura roga - pasina kunobatanidza gametes. Chaizvoizvo bereka amoeba, ciliates shangu, nezvimwe majemusi. Ona kuti izvi kunoderedza variability muviri kuti chinhu. The "loophole" chete chaiwo vakasarudzwa zvipenyu chete-celled - iyi inongova asingashumbi mutation.

Nokudaro, kubereka zvinomera nemhuka kuitika asexually - a kubereka yavo mhando, kwete chokuita Exchange pakati vanhu vaviri majini mashoko.

Nzira asexual kubereka

Kamwe isu afunga chii chinonzi asexual kubereka, hazvina chiya kutaura, uye nzira dzake, izvo pane zvakawanda. First - weboka iri. Kubva kana mumwe chete akadai amoeba kuumba mamwe maviri - subsidiaries. Musimboti anotanga kugovera, kuti cytoplasm anotanga kuputsa migove miviri. nzira yechipiri - a kubereka vana spores kana spore inotungamirwa. Zvinoda nharo zvipuka zvine masero akawanda zvinenge zvakadai semiti kana notumwe. Kunokosha! Chirwere spores hadzina muzvirongwa kubereka somunhu utachiona anokwanisa rokuumba mumwe chete spore. Akatevera nzira - yotunga. Saka reproduces Somuenzaniso, nyore coelenterates - Hydra. Vemumapato vanhu aumba kubva "mai" muviri. Panzira, yotunga uye fission inzira chaiye asexual kubereka - vegetative. Kuti uwane izvi, isu tsanangura pazasi. Ichiparara asexual kubereka nzira vane Somuenzaniso Starfish. Zvinoitika seizvi: muviri "Amai" anotanga kugovera migove. Mumwe nomumwe wavo anova chikamu muviri. Vegetative kubereka kwemhuka uye zvinomera

nzira inokosha asexual kubereka zvinomera uye mhuka dzakaderera - vegetative. Kubereka kunoitika kuburikidza vegetative nhengo, zvakadai midzi, mashizha kana dzakachinjwa Matavi. Somuenzaniso, mahabhurosi Anowanza midzi (ona nhamba), Violet - mashizha, uye zvichingodaro. Nenzira, inonyanya kufarirwa nzira iyi kubereka pakati pevara zvinomera dzomusango. In mashoko zvipenyu, chirongwa kubereka zvinomera nokuda chido kudzorera vakarasika nhengo dzavo. Kubereka vegetatively anogona kupfuura zvose sezvingatarisirwa uye artificially, semuenzaniso, achishandisa munhu. Nomutowo uyu, kubereka uye miti yakawanda, vakakwanisa bereka zvepabonde. In mhuka, vegetative nzira rinoitwa weboka kana yotunga.

Saka, vazhinji dzokubereka nzira ari muenzaniso yavo inotiratidza chinonzi asexual kubereka.
