I-photosynthesis

Umzobo we-photosynthesis kwizityalo. Ii-carbohydrates ezivelisiweyo ziyagcinwa okanye zisetyenziswe zizityalo.

Uwonke umyinge wohlobo lwe-photosynthesis eyenzeka kwizityalo

umfanekiso opheleleyo obonisa ukusasazeka kwe-photosynthesis kulo lonke ilizwe, nakuzo zombini ulwandle i-phytoplankton nomhlaba kunye nohlaza lwawo.

I-Photosynthesis yinkqubo esetyenziswa zizityalo nazezinye izidalwa eziphilayo ukuguqula amandla okukhanya, okuhlala kuvela elangeni, abe ngamandla e-chemical ayakuthi akhutshwe kamva ukuze aye kutha amandla kwimisebenzi eyenziwa zezi zidalwa ziphilayo. Laa mandla echemical agcinwa kwii-molecules ze-carbohydrate, ezifana neswekile, edidiyelwa ngecarbon dioxide nangamanzi – yiyo le nto kusetyenziswa igama elithi 'photosynthesis', elivela kwisiGrike φῶς, phōs, "ukukhanya", kunye σύνθεσις, nokudidiyela, "ukuxuba". Kumaxesha amaninzi, i-oxygen ichithelwa ngaphandle komzimba wento ephilayo njengokungcola. inkoliso yezityalo, inkoliso yee-algae, nee-cyanobacteria zenza i-photosynthesis; ezo zidalwa ke kuthiwa zii-photoautotrophs. I-Photosynthesis igcina i-atmospheric oxygen ikumgangatho ofanelekileyo ize inakekele zonke ii-organic compounds noninzi lwamandla afunekayo kubomi bezinto ezisemhlabeni.
