I- amahomoni yizinto ezenziwe yi izindlala ze-endocrine, okuthi lapho ekhishelwa egazini kukhiqize ukwenziwa okuthile kwezinqubo ezithile, futhi ngale ndlela kwasebenza ezinye izitho zomzimba.
Ngale ndlela, ezilwaneni ama-hormone ayihlobo lwe izithunywa ehlanganisa imisebenzi yezingxenye ezahlukahlukene zomzimba, efinyelela kuwo wonke amaphethelo kuye ngokuhamba kwegazi, nokufeza izinguquko ezifana nokusheshisa kokugayeka kokudla nokushaya kwenhliziyo, ukukhiqizwa ubisi noma ukukhula kwezitho zocansi.
Zonke izindlela ze- izinto eziningi eziphilayo khiqiza ama-hormone: lawa zivela kuzo zombili izilwane nezitshalo. Kodwa-ke, njengasesimweni sokuqala, umzimba unemisebenzi eminingi eyengeziwe. izinhlobo zamahomoni zehlukahluka kakhulu, kanti kwesesibili zikhawulelwe eqenjini elifushane.
I- ama-hormone ezilwane yizinto ezihanjiswa ngempumelelo ngokuhamba kwegazi, futhi zinomphumela wazo ezithweni ezithile noma kwizicubu, kuso iseli ezihlanganisa noma ngamangqamuzana ahlanganayo, angenelele kunqubo eyaziwa ngokuthi ukuxhumana kwamaselula.
AmaHormone angaba ngemvelo noma enziwe, futhi ajwayele ukusetshenziselwa ngenhloso kwezinye izinkinga zempilo. Okukhethekile kwezokwelapha okubhekele ukutadisha izifo zehomoni yi endocrinology, futhi inezifo ezivame kakhulu ezelapha isifo sikashukela, i-hypothyroidism noma i-hyperthyroidism.

Phakathi kwemisebenzi eyenziwa ngamahomoni, ukusetshenziswa nokugcinwa kwamandla kuyagqama; ukukhula, ukuthuthukiswa kanye nokuzala; ukugcina amazinga egazi oketshezi, usawoti, noshukela; ukwakheka kwamathambo nemisipha; futhi ekugcineni ukuguquguquka kokuphendula kwezinhlelo zezinzwa nezemoto phambi kwezinhlobonhlobo ezahlukahlukene.
Ezilwaneni, ama-hormone akhishwa yizindlala ze-endocrine ezingangeni emzimbeni ngqo egazini.

Uma kwenzeka kuba imifino, ama-hormone aqanjwa ngegama ama-phytohormones, futhi zilawula ikakhulu izimo zomzimba zezitshalo. Akhiqizwa ngamanani amancane ezicutshini zezitshalo, kusukela kuleli klasi le- izidalwa eziphilayo ayinazo izindlala.
Imikhumbi yilezo ezivumela ukuthuthwa esimweni samahomoni ezitshalo, abuye abeke izenzeko zokuphikisana nokulinganisela kwamahomoni, okuholela ekulawulweni okuqondile kwemisebenzi yezitshalo: ngale ndlela ukungabi khona kohlelo lwezinzwa kuyaxazululwa.
Izici
I- tshala ama-hormone Zenziwe yisitshalo, zitholakala ezindaweni eziphansi kakhulu ngaphakathi kwezicubu, futhi zingasebenza endaweni yokuhlanganiswa kwazo noma kwezinye. Izitshalo ezisezingeni lezicubu zazo zikhiqiza nezinto ezinciphisa noma ezivimbela ukukhula, futhi kwesinye isikhathi into efanayo ikhiqiza imiphumela ephikisanayo ngokuya ngezicubu lapho kuphendulwa khona.
Ama-hormone ezitshalo alawula inqwaba yemicimbi: ukukhula kwezitshalo, ukwehla kwamaqabunga, ukuqhakaza kwezimbali, ukwakheka kwezithelo nokuhluma.
Izibonelo zamahomoni ezitshalo
Zihlukaniswe zaba zinhlanu, futhi zibhalwe ngezansi ngomsebenzi wazo oyinhloko:
- Ama-Auxins: Ukuvuthwa kwezithelo, ukukhula okumi mpo kwesitshalo nokuqhakaza kuncike kumahomoni alolu hlobo.
- Ama-cytokinins: Zisheshisa ukuhlukaniswa kwamaseli noma i-mitosis, zibangele ukuthi isitshalo sikhule ndawonye nezinsimbi.
- I-Gibberellins: Zibangela ukukhula kwesiqu namaqabunga, nokuhluma kwembewu.
- I-Ethylene: AmaHormone abangela ukuvuthwa kwezithelo, ukuguga kwesitshalo nokuwa kwamaqabunga, izimbali nezithelo.
- Ama-Abcisic acid: IHormone enemiphumela yokuvimbela, njengoba ivimbela ukukhula kwesiqu.
