Waa maxay sawir-qaadista?
Context:Farsamaynta iftiinka waa hab ay dhirtu iyo noolaha kale u isticmaalaan inay tamarta iftiinka u beddelaan tamar kiimiko ah oo, neefsashada unugyada, ka dib la sii deyn karo si loo kiciyo dhaqdhaqaaqa noolaha. Qeyb ka mid ah tamarta kiimikada ah waxaa lagu kaydiyaa molecules carbohydrate, sida sonkorta iyo macmacaanka, kuwaas oo laga soo saaro kaarboon dioxide iyo biyo <unk> sidaas awgeed magaca photosynthesis, oo ka soo jeeda Giriigga phōs (φῶς), "iftiin", iyo synthesis (σύνθεσις), "isugu keen". Dhirta badankeeda, algae, iyo cyanobacteria waxay sameeyaan fotosynthesis; noolaha noocan ah waxaa loo yaqaan photoautotrophs. Waxyaabaha loo yaqaano photosynthesis ayaa inta badan mas'uul ka ah soo saarista iyo ilaalinta oksijiinta hawada ee dhulka, waxayna bixisaa inta badan tamarta lagama maarmaanka u ah nolosha dhulka.  Inkastoo habka loo yaqaano photosynthesis ay ku kala duwan yihiin noocyada kala duwan ee noolaha, habkaasi wuxuu had iyo jeer bilaabmaa marka tamarta iftiinka ay nuugaan borotiinno la yiraahdo xarumaha falcelinta oo ay ku jiraan chlorophyll cagaaran (iyo midabyo kale) midabyo/chromophores. Dhirta, borotiinkani waxay ku jiraan unugyada loo yaqaano chloroplasts, kuwaas oo ku badan unugyada caleemaha, halka bakteeriyada ay ku jiraan xuubka plasma. Isbeddelladan iftiinka ku tiirsan, xoogaa tamar ah ayaa loo isticmaalaa in elektaroonnada laga saaro walxaha ku habboon, sida biyaha, oo soo saara gaaska oksijiinta. Hydrogen-ka ka soo baxa kala-goynta biyaha waxaa loo adeegsadaa abuurista laba xarumood oo kale oo u adeega sida kaydinta tamarta muddada-gaaban, taasoo u oggolaaneysa wareejinta si ay u wado fal-celinno kale: xarumahaan waa la yareeyay nicotinamide adenine dinucleotide phosphate (NADPH) iyo adenosine triphosphate (ATP), "lacagta tamarta" ee unugyada.
Waxyaabaha loo yaqaano (photosynthesis) - Hab ay dhirtu iyo noolaha kale u beddelaan tamarta iftiinka tamar kiimiko - Eray ka soo jeeda Giriigga phōs (φῶς), "iftiin", iyo synthesis (σύνθεσις), "isugu keen" - Waa hab mar walba billaabata marka tamarta iftiinka ay nuugaan borotiinka loo yaqaanno xarumaha falcelinta - waxaa si kala duwan u sameeya noocyada kala duwan - waxay si weyn mas'uul uga tahay soo saarista iyo ilaalinta oksijiinta hawada ee dhulka
