Waa maxay muhiimadda noolaha faafin ah asexual in dhirta?

Kordhinta tirada dadka ee noocyada ah - hawsha ugu muhiimsan ee u shaqeeyo kasta. Taasi waa sababta, oo ay la socdaan dhalmo galmada asexual muuqday. Geedaha ku habboon ay faafinta wax ku ool ah, iyadoo la isticmaalayo xubnaha jidhkiisa. Waa maxay muhiimadda noolaha faafin ah asexual? Waa maxay faa'iidada iyo khasaaraha ee habkan?

Waa maxay dhalmo asexual?

Mid ka mid ah gool of jiritaanka shaqeeyo nolol - ciyaaro dhala u gaar ah. Si loo xalliyo dhibaatada this, dhirta, xayawaanka, bakteeriyada, iyo xubnaha kale ee adduunka noolaha ayaa siyaabo iyaga u gaar ah in la kordhiyo tirada helay. No dhalmo yaab lagu qoray mid ka mid ah xuduudaha oo dhan nolosha ay la socdaan koritaanka, Dheef tamar, samrana deegaanka gudaha, iyo wixii la mid ah. D.

dhalmo Asexual - waa habka ka qaybgalka unugyada jeermiga looma baahna. Gametes ka ciyaaraan door muhiim ah in formation of embriyaha wax hidde cusub, si kastaba ha ahaatee, ma aha had iyo jeer suurto gal ah in ay u baddashaan habka taranka galmada. Waa maxay muhiimadda noolaha faafin ah asexual?

Waayo, noolaha qaarkood, sida bakteeriyada - waa habka kaliya ee si loo kordhiyo baaxadda dadweynaha. Waayo, inta kale ee xoolaha iyo dunida geedka asexual iyo dhalmo galmada ayaa loo baahan yahay in qiyaas siman. Haddii hore oo kale waxaa loo isticmaalaa kororka tirada tirada, kii labaadna wuxuu ahaa - tayada (ie isbedel ah waxyaabaha hidaha).

Noocyada dhalmo asexual

Playing dhala u gaar ah ee xawaaraha sare - taasi waxa weeye waxa ay tahay muhiimadda noolaha faafin ah asexual ee noolaha. Noocan ah dhalmo waa ka weyn, oo sidaas daraaddeed danbow Lagaga ay horumarinta u hooseeya ee u shaqeeyo. Next loo soo bandhigi doonaa noocyada dhalmo asexual, kaas oo dhici kara in kooxaha Qorxeey kala duwan.

1. fission Binary. Noocan ah dhalmo waa caadiga ah ee inta badan oo ka mid ah wakiilo ka prokaryotes iyo protozoa. unugyada foomamka xijaab transverse taas oo kala qaybinaya qeybtii, oon la xirrira laba unugyada gabadhiisa.
2. Schizogony. Habkani waxa loo arki karaa version la hagaajiyey ee horyaalka binary, markii mid ka mid ah unugyada yeesho dhowr shuraakada. First core kala qaybiyey, ka dibna - unug laftiisa. Noocan ah faafinta laga dheehan karo in wareegga nolosha Sporozoa (tus, plasmodium falciparum), iyo qaar ka mid ah algae.
3. Gaysashada. In kasta oo xog ah ee fission binary iyo schizogony, ma dhammaan noolaha, hababka taranta u noqon karaan wax ku ool ah. Waayo, kuwanu metazoans heer hoose ah, sida Coelenterates, lagu gartaa gaysashada - formation of jidhka cusub ee farac foomka, taas oo marka hore ku xiran qofka waalidka, ka dibna off. Haddii noocan oo kale ah "kelyaha" aan la jaray, u sameeyaan deegaanada dhowr noolaha. Gaysashada sidoo kale waa sifo khamiirka.
4. Qaybsanaanta. Tani taranka waxay ku salaysan tahay nooca awooda jirka ee koriya. Waa caan ku planarians, nemerteans, buushka, qaar ka mid ah algae filamentous. Marka farsamo shaqsi waalidka dhaawac loo qaybin karaa dhowr qaybood, kuwaasoo mid walba uu ku siinayaa kor u qaada jirka cusub.
5. Sporulation ama formation spore. Nooca ugu horusocod faafin ah asexual, tan iyo formation of khilaafka waa is waydaarsiga in macluumaad hidde. Sidaas darteed, genotype ee Faracoodii waa xoogaa ka duwan in shimbirraha waalidka. Sporulation oo laga dheehan karo in fangaska, algae, horsetails, ferns, ajada, ajada.

Waa maxay muhiimadda noolaha faafin ah asexual dhirta?

boqortooyada warshad wuxuu u qaybsan yahay spore iyo farcankaaga. hore waxaa ka mid ah Muuse, horsetails, Muuse kooxda, ferns, iyo labaad - gymnosperms iyo angiosperms. dhalmo Asexual dhirta spore waa inta badan ee formation of kudka. In gymnosperms iyo angiosperms sporulation weli sidii tallaabo dhexe ee bixitaanka gametes (microspores iyo megaspory). Dhalmada adigoo isticmaalaya xubnaha jirka ee - in uu yahay waxa ay tahay muhiimadda noolaha faafin ah asexual in dhirta.

dhalmo daaqsinka waa dabeecadda oo kaliya noocyada xeel of flora, iyo sidoo kale waa nooca keliya ee dhalmo asexual. In habkan of spore waa mid aad u dhif ah. Taasi waa arrin kale, waxa waa ahmiyaddii noolaha faafin ah asexual in dhirta.

Sidee taranka ee noocyada ugu vegetatively?

1. Bedelida of asliga ah. Waxaa ka mid ah nalalka, corms, rhizomes, stolons, tubers, shaarib. At xubnaha dhirta, kuwaas oo loo sameeyay ku hari aasaasi ka kaas oo caleemaha cusub koraan. Qaabkan faafin ah waxaa laga heli karaa at the Tulip, Narkisos, basasha, blackberries, iris, strawberries, baradho iyo wixii la mid ah. D.
2. tubers Root (korneklubni). meydadka Kuwanu waa xididdada adventitious, kuwaas oo kaydsato nafaqooyinka. Korneklubnyami buluug sirdoonka, Yeruusaalem artichoke, Dahlia.
3. Gooyn. Wadaagista - waa qayb ka mid ah asliga ah, taas oo ka kooban ugu yaraan hal Guntin la hari adventitious. Mararka qaarkood ku filan in nooc sheet oo aan asliga ah. Tusaale ahaan dhirta: Begonia, fuchsia, Dracaena, iwm ...

Doorka noolaha faafin ah asexual dhirta

formation gamete Hab-xidhan tahay qodobo badan. Inta badan, dhalmo asexual noqon karaa mid wax ku ool ah, maxaa yeelay waxa ay la fulin karo iyada oo aan ku lug of gametes. Wixii dhirta spore waxaa dhammaantiis waa qayb ka ugu weyn ee wareegga nolosha. Waayo, abuur - dhalmo ah daaqsinka, taas oo aad si fudud u kordhin kartaa tirada dadka.

Waa maxay muhiimadda noolaha faafin ah asexual? Tani ma xawaaraha oo keliya, laakiin sidoo kale ka nasan doonaa geedi socodka fulinta. Haddii dhalmo galmada xaaladaha deegaanka si mug leh loo baahan yahay ee maturity ee warshadda, asexual ku dhici karaa ku dhawaad waqti kasta oo nolosha ka mid ah shakhsiga.

Si kastaba ha ahaatee, faafinta daaqsinka waxay leedahay cillado ay. Tusaale ahaan, iyada oo noocan ah dhalmo jiro dhaafsiga macluumaadka hidaha. Taas macnaheedu waa in warshadda aan ku habboon tirada dadka qarniyada xaaladaha cusub ee deegaanka, iyo tan waxay keeni kartaa in ka mid ah dadka of clones ka helay.

Isticmaalka dhalmo asexual aadanaha ee dhirta

Geedi socodka ah ee taranka waxaa si balaadhan looga isticmaalaa in ganacsiga. dhalmo daaqsinka ah ee dhirta u ogolaanaya in ay ku beeran wadooyin weyn ee baradho ah dalka, basasha, xididdo, karootada, strawberries, strawberry iyo wixii la mid ah D..

Sidoo kale faafinta daaqsinka ogolaanaya in la kordhiyo xaddiga calafka xoolaha, cuntada, dalagyada ornamental, kor loogu qaado iska caabin ah dhirta si ay xaaladaha deegaanka loo kasin via kulantay.
