Ziyini izingxenye, izici nokusebenza kwembali?

Kulesi sihloko sizokuvuselela konke okumele kwazi ngembali njengengxenye ebalulekile yesitshalo, imisebenzi yaso, izici, njll., ngakho-ke ungaphuthelwa le ndatshana ethokozisayo.

Imbali uhlelo lokuzala lwesitshalo Umsebenzi wawo ukukhiqiza imbewu eqinisekisa izizukulwane ezintsha zezitshalo futhi ngalezi ukuqhubeka kohlobo kanye nokusakazwa kwalo kunikezwa.

Ziyini izingxenye zembali?

Zinezitho ezine, ezimbili ezibalulekile okuyizinto i-androecium ne-gynoecium nezesekeli ezimbili okungukuthi calyx futhi corolla.

Okuvamile ukubona ukuthi imbali isekelwa kanjani i-peduncle enezimbali enwebekayo ukuze imise isitsha lapho kufakwa khona izitho ezi-4 zembali esisanda kuzibalula. Imbali ingahanjiswa njengeyodwa noma ndawonye nabanye ngesimo sezimbali.

I-Chalice

Yakhiwa ngama-sepals ngokuvamile aluhlaza, kuya ngembali le ahlelwe ngokwahlukana noma anamathiselwe komunye nomunyeNgokunjalo, ukwakheka kwayo kungafana noma kujwayelekile, kuhluke noma kungalingani.

ICorolla

Noma amacembe, ahlelwe azungeze imbali njengesivikelo Kulokhu, zivame ukuba nombala kodwa futhi zingaba luhlaza, konke lokhu kuzoya ngesitshalo. Amacembe ethulwa ngezindlela ezahlukahlukene, ahlukaniswe kahle, anamathiselwe, osayizi abahlukene, anezimo ezahlukahlukene futhi anomsebenzi obaluleke kakhulu kuveza iphunga lesici sesitshalo ngasinye ukuheha izinambuzane nokukhuthaza inqubo yokuvota impova.

I-Androecium

Kuyisethi ye-stamens enembali, nayo eyiyo tshala isitho sokuzala sowesilisa. Izingxenye zayo ziyintambo kanye ne-anther, eyokugcina iqukethe amasaka amabili empova lapho kulwelwa khona izinhlamvu zempova.

I-Gyneceous

Iyingxenye emaphakathi yembali futhi iyisitho sowesifazane salokhu, yakhiwa ngamaqabunga amaningana abizwa ngokuthi ama-carpels, i-ovary efakwa esitsheni futhi iqukethe ama-ovules, isitayela sesimo se-cylindrical futhi equkethe izicubu zesiponji futhi inhlamba ephethe i- khiqiza iziphuzo ezinoshukela ezondla impova.

Singaphetha ngokuthi izici zocansi zesitshalo yilezi:

Ovule

Yakhiwe ngaphakathi kwayo yi-nucela kanye ne-peduncle eyihlanganisa ne-placenta, ngokuba yinto yezocansi yabesifazane.

Impova

Isici sobulili sowesilisa, kuyimpuphu enhle kakhulu leyo ikhiqizwa emasakeni empova umbala wayo ungahluka kusuka ophuzi uye kwamanye ama-shades.

Inqubo yokuthuthwa kwempova

Kuyinqubo eqondile noma engaqondile lapho kudluliswa khona impova kusuka ku-anther kuya enhlazweni. Kuthiwa iqonde ngqo lapho inqubo yokuvotela impova ivela embalini efanayo, ukuze lokho kwenzeke kungenzeka i-hermaphrodite.

Akuqondile lapho impova yembali ifinyelela ukucwaswa kolunye uhlobo olufanayo, lokhu kungenxa yokungenelela kwezinhlaka zangaphandle futhi yiyona eyenzeka kaningi.

Lawa ma-ejenti angaphandle yilezi:

Umoya

Ithwalwa isuswa kwesinye isitshalo iye kwesinye ngenxa yokukhanya kwayo, le nqubo ibizwa nge-anemophilia.

Izinambuzane

ngqo izimvemvane nezinyosi ezidonswa yiphunga elikhishwa yizimbali ezithile, zehlela kuzo ukuthola umpe wazo futhi umzimba wazo nemilenze kukhulelwe izinhlamvu zempova eziziphethe zizibeke kwezinye. Lokhu kubizwa nge-entomophilia.

Izinyoni

Zisebenza njengezinambuzane, zithwala impova kusuka embali eyodwa kuya kwenye. Ibizwa ngokuthi i-Ornithophilia.

Amanzi

Izimbali ezintanta emanzini lapho zingqubuzana zidlulisa impova. Ibizwa ngokuthi yi-Hydrophilicity.

Indoda

Ikwenza lokho ngokutadisha izitshalo noma ukukhiqiza izitshalo ezilawulwayo, izinhlobo ezintsha zezitshalo noma ukuqinisekisa ukukhiqizwa.
