Siphendula umbuzo ngokuthi kungani utshani buhlaza

Ngokuvamile kwenzeka ukuthi izinto ezilula zidinga incazelo elula. Umbuzo wezingane mayelana nokuthi utshani obuluhlaza bubeka abantu abaningi abadala, uma kungenjalo ekupheleni kokufa, kube sesimweni esinzima kakhulu. Naphezu kokuthi lesi sihloko sivela emkhakheni wekharikhulamu yesikole, akubona wonke umuntu ongakhumbula amagama afana ne-photosynthesis noma i-chlorophyll, engakhulumi ngezinqubo ezihlobene nazo.

Impendulo embuzweni wokuthi kungani utshani buhlaza kulesi siza. Okokuqala, kubalulekile ukuqonda inqubo yokwakheka kokubona okukhanyayo kubantu. Ama-shades amehlo ethu abhekayo awaxhomeki esikalini sombala, kodwa ngokucabangela ngaphansi kwesenzo selanga eliqondile. Le ncazelo isondelene kakhulu nesinye sezimpendulo eziyinhloko. Etshanini liqukethe into ekhethekile - i-chlorophyll, okusho ngesiGreki ukuthi "ihlamvu elihlaza". I-Chlorophyll ithatha yonke imidwebo ye-shades, ngaphandle kweyodwa. Kulula ukuqagela ukuthi lokhu kungumbala wezitshalo zasehlobo.

Kukhona futhi inguqulo yesibili yempendulo yombuzo othi kungani utshani buhlaza. Nguye ovame ukushiwo ezincwadini zesikole futhi esiseduze neqiniso. Ngokwesizathu salo futhi lilele okuqukethwe kwe-chlorophyll enotshani. Izinto ezinjalo azikona nje kuphela ukusetshenziswa kwe- carbon dioxide nokukhiqizwa kwe-oksijeni, okudingeka kakhulu ekuphileni komuntu, kodwa futhi i-pigment ekhethekile ephethe umbala ohlaza ohlaza. Ososayensi baye bafakazela ukuthi izingxenye ze-chlorophyll ziyi-green ngempela. Umbala wabo uhlotshaniswa nokuqukethwe kwe-magnesium, okuphethwe ukudala lo mthunzi wemvelo. Ezitshalweni, kunezinye izingulube eziningi ezinemibala eziqukethwe, nakuba zilinganiselwe kakhulu. Sibonga kubo, utshani obuluhlaza ngezinye izikhathi bangathatha izinhlobo eziningi ze-shades.

Ukusetshenziswa kwe-chlorophyll ezindabeni zansuku zonke zesayensi namuhla kusengaphezu kwamandla. Izingxenye zalo azikwazi ukugcinwa futhi ngokushesha zishintsha ithoni yazo ejabulisayo kumbala ogqamile ongenayo. Kodwa-ke, manje kunemibala eminingi yokufakelwa esekelwe kulolu lwazi oluwusizo lwemvelo.

Ngakho-ke, i-chlorophyll ayigcini nje ukuletha ubuhle emhlabeni osizungezile futhi isisiza ukuba siphendule umbuzo we-classic wokuthi kungani utshani buhlaza, kodwa futhi luyisici esibaluleke kakhulu. Inhloso yalo enkulu ukukhiqiza oksijeni edingeka kakhulu - isisekelo sokuphila kwesintu sonke.

Le nqubo ibizwa ngokuthi i-photosynthesis futhi iqhutshwa ngokuphelele yibo bonke abamele izitshalo emhlabeni. Uma kufushane ukuchaza izigaba zayo eziyinhloko, isithombe esilandelayo sizotholakala: sithatha i- carbon dioxide ngaphansi kwethonya lokuphendula kwamakhemikhali, kukho ukuhanjiswa kwama-electron kusuka ku-hydrogen namanzi, okwenza kube nokwakhiwa kwama-carbohydrate nokukhululwa kwe-oksijeni.

Ngaphezu kwalokho, ekwenzeni i- photosynthesis enotshini namahlamvu, kutholakala izakhi eziningi eziwusizo, ezifana noshukela, isitashi, amaprotheni.

Utshani luhlaza, i-chlorophyll iqukethe kakhulu, ngakho-ke iphakamisa izinzuzo ezingayiletha emhlabeni.
