Ngaba wakha wazibuza ukuba kutheni phantse zonke izityalo ziluhlaza? Ukuba kunjalo, usenokuba ukhe weva nge<em>chlorophyll, esisidali-bala esifumaneka kuzo zonke iindawo eziluhlaza, njengamagqabi, yaye kwezinye iimeko nakwisiqu, iintyatyambo, kwaneengcambu (njengakwizityalo) zePhalaenopsis orchids) .
Kodwa impendulo yalo mbuzo ayikho lula njengoko ibonakala. Ewe, kungenxa yeklorofili, kodwa...ikwanento eninzi yokwenza neliso kwaye, ngaphezu kwako konke, nengqondo., ekubeni kungumbulelo kuye kuba ‘sikwazi ukubona’, ekubeni inguye odibanisa inkcazelo ayifumana kwingqayi yamehlo aze avelise imibala esiyibonayo kamva. Akunjalo kuphela: kuxhomekeke ekubeni ungumntu, inja, ikati okanye esinye isilwanyana, uya kukwazi ukubona kuphela inani elithile lemibala kunye nobukhulu obukhulu okanye obuncinci kunezinye izidalwa eziphilayo.
Abantu bayibona njani imibala?

Ixesha elide kakhulu, kwaye sithetha malunga neminyaka eyiwaka, kwakukholelwa ukuba abantu babona ngamehlo abo. Oku kusengqiqweni, hayi ilize, zizitho ezisidibanisa nengaphandle. Rhoqo kusasa, into yokuqala esiyenzayo kukuzivula ukuze siqale usuku lwethu nosuku. Xa sineengxaki zombono, ezifana ne-myopia, i-ophthalmologist (okanye ugqirha wamehlo) uya kusixelela indlela yokunyamekela amehlo ethu kunye nento esinokuyenza ukuze asebenze.
Into abangasixeleli yona, mhlawumbi ngenxa yokuba singabuzanga, yileyo zii<em>neuron zobuchopho ezinoxanduva lokucacisa lonke ulwazi olubonwa ngamehlo ethu. Ukuyicacisa ngendlela elula, bekuya kuba ngathi sifuna ukufunda ulwimi esingalwaziyo kwaphela, njengesiTshayina okanye isiJapan. Ekuqaleni, sasidla ngokubona iimpawu ezingaqhelekanga, kodwa ngokuthe ngcembe, ngenxa yofundisiso, sasifunda ukufunda ngolo lwimi.
Njengokuba. Amehlo abona le miqondiso ingaqhelekanga, kwaye bubuchopho obunika intsingiselo. Yiyo loo nto sinokuthi "le yindlela elikhangeleka ngayo ihlabathi". Kodwa, siyibona njani imibala
Kholwa okanye ungakholwa, imibala ayikho, okanye kunoko, ukukhanya ngumbala, kwaye yiloo nto iliso liyibambayo. Kuyo sifumana iindidi ezimbini zeeseli, iintonga kunye neecones, ezinoxanduva lokuqokelela iindawo ezahlukeneyo zokukhanya kwelanga, imibala, ebonakaliswa kumphezulu., yaye zizo ezithunyelwa zikwimo yamandla ombane ebuchotsheni ukuze ikwazi ukuzitolika.
Kwiliso lomntu, ezi seli ziyayiva imibala eluhlaza, eluhlaza, nebomvu. Ngokomzekelo, xa sibona intyatyambo etyheli, kungenxa yokuba ezo seli zinovelwano kuluhlaza nabomvu ziye zavuselelwa ngaxeshanye.. Kwaye ukuba sibona izityalo ezininzi eziluhlaza, kungenxa yokuba lo mbala ngumbala obonakala kuzo xa ukukhanya kuzibetha.

Kodwa kusekho okungakumbi: kuxhomekeke kwindlela obuyiyo loo mphezulu kunye nohlobo lokukhanya olubonakalisiweyo, eminye imibala okanye eminye iyakubonwa ngokuxhomekeke kubude bayo.. Kwaye nangona kukho iigrafu ezisebenzayo ukusinika umbono wokuba ziyintoni na ezi, sinokuthi akukho namnye kuthi obona umhlaba ngendlela efanayo: nokuba kungenxa yokuba banengxaki yombono, okanye ebuchotsheni, okanye ngenxa yokuba babona umhlaba ufana. indalo ibenza balibone ihlabathi ngendlela abalibona ngayo.
Kutheni izityalo ezininzi ziluhlaza?

Uhlaza ngumbala esihambelana nobomi kunye nendalo. Uninzi lwezityalo lujonge lo mbala, kuba nguwo obonakaliswa kumphezulu wazo xa ukukhanya kuzibetha. Kodwa kutheni? ngenxa yeklorofili.
I-Chlorophyll yi-pigment efumaneka kwizityalo, kodwa nakwezinye i-algae. Kubalulekile ukuze bakwazi ukwenza iphotosynthesis, kwaye ke ukuze bakwazi ukuguqula amandla elanga kwaye bawaguqule abe ngamandla. Kodwa kwakhona yeyona nto ibanika umbala oluhlaza, kuba ifunxa ukukhanya kumbala oluhlaza, obomvu nobomvu, kwaye ibonakalisa uhlaza..
Izityalo ezingahlaza zenza njani ifotosynthesize?
Sithe i-chlorophyll ibalulekile kubo ukuze benze ifotosynthesize, kodwa kuthekani ngezityalo ezinombala ongengoluhlaza? Ezi ziqulathe kuphela iklorofili kwiindawo zazo eziluhlaza, ukuba zikhona; kungenjalo, amanqanaba abo e-carotenoids, olunye uhlobo lwe-photosynthetic pigment, ingaba phezulu kakhulu kunezityalo eziluhlaza.
Umzekelo, ezi zizinto ezenza iminqathe eziorenji, iGalia melon ibe tyheli, okanye imaple yaseJapan ibe bomvu… kakuhle, mfusa (hayi ncam bomvu).
Oku akuthethi ukuba izityalo eziluhlaza azinayo i-carotenoids, njengoko kunjalo., kodwa kubo ii<em>chlorophyll ziluncedo ngakumbi.
