Kuyini ukukhiqizwa kabusha asexual ngokuthi izilwane nezitshalo

Lokuzaliswa eziphilayo - kabusha abantu zokuzala njengazo, ne iqhaza ngezindaba zobulili ngenxa amaseli kwabo bobabili abashadile, ngakho-ke kubhekwa ngokobulili ngokwakhona. Lesi isici sobuntu zonke eziphilayo emhlabeni. Nale ecacile zonke. Manje ake sibone ukuthi yini ngokuthi ukukhiqizwa kabusha asexual, nezindlela lapho kwenzeka.

Lokho okubizwa ngokuthi ukukhiqizwa kabusha asexual

Ngaphambi Ekuthathweni lo mqondo, siphawula ukuthi ifomu ukuveza asexual kuvamile zombili izinto eziphilayo ezinamangqamuzana amaningi futhi unicellular. Abangenalo umkhondo, chaza ukuthi ekuqaleni izitshalo kanye isikhunta, futhi owesibili - eziphilayo eliphilayo elilula (ezifana amoeba). Igama le ndlela yokuzala liyazikhulumela - ngaphandle ukubandakanywa gametes. Uqinisile nokuzala amoeba, ciliates izicathulo nezinye izimpahla ezincane ezingabonakali ngeso lenyama. Qaphela ukuthi lokhu kunciphisa kokuhlukana yomzimba lutho. I "maphutha" kuphela kwemvelo eziphilayo owumphumela - lena nje kuguquka okungahleliwe.

Ngakho, ukukhiqizwa zezitshalo nezilwane okwenzeka asexually - kabusha uhlobo zabo siqu, hhayi elihlobene ne-exchange emkhatsini ezimbili zabantu ukwaziswa kwezakhi zofuzo.

Izindlela ukuveza asexual

Uma sesithole esiphethweni lokho okubizwa ngokuthi ukukhiqizwa kabusha asexual, akusiyo engadingekile ukubalula, nezindlela zakhe, lapho kukhona abaningi. Okokuqala - lokhu kwehlukana. Kusukela nomuntu ngamunye, ezifana amoeba zakha ezinye ezimbili - ezingaphansi. I-nucleus uqala zazibangela ukwehlukana, cytoplasm uqala ukuhlukana nomuntu obuthandana naye zibe izingxenye ezimbili. Eyesibili indlela - kabusha ezinhlamvu noma spore kumiswa. Kudinga Ziphikisana eziphilayo ezinamangqamuzana amaningi ezifana izitshalo noma isikhunta. Okubalulekile! ezinhlamvu Amagcikwane azisetshenziswa yokuzala njengoba igciwane uyakwazi ukwakha spore eyodwa kuphela. Indlela elilandelayo - luthela. Ngakho-ke eveza, isibonelo, coelenterates elula - Hydra. abantu Okuphethwe kwakhiwa kusukela "umama" umzimba. By the way, luthela kanye ukuqoqwa ayindlela ekhethekile ukuveza asexual - vegetative. Ukuze uthole olunye ulwazi ngalokhu, senza uchaze ngezansi. Fragmented asexual ukukhiqizwa kabusha indlela babe, isibonelo i-starfish. Kwenzeka kanje: umzimba "umama" uqala wahlukanise izingxenye. Ngamunye wabo iba umzimba osizayo. ukukhiqizwa kabusha vegetative e izilwane kanye nezitshalo

indlela Special asexual kabusha izitshalo nezilwane ephansi - vegetative. Lokuzaliswa kwenzeka esebenzisa izitho vegetative, ezifana izimpande, amaqabunga noma amahlumela ukushintshwa. Ngokwesibonelo, ama-raspberry esandisa izimpande (bheka isithombe), violet - amahlamvu, nokunye. By the way, ethandwa kakhulu le ndlela yokuzala phakathi ukusetshenziswa izitshalo zasendle. Ngamagama yezinto eziphilayo, inqubo kabusha izitshalo ngenxa isifiso ukubuyisela izingxenye abalahlekile. Lokuzaliswa vegetatively izophela kokubili ngokwemvelo futhi okwenziwe isib ngokusebenzisa abantu. Ngale ndlela, ukukhiqiza kabusha abe izitshalo eziningi, siyakwazi nokuzala ngokobulili. Ezilwaneni, indlela vegetative Kwenziwa division noma luthela.

Ngakho, abaningana impela ekuzaleni ngesibonelo yabo usibonisa ukuthi ibizwa ngokuthi ukukhiqizwa kabusha asexual.
