I-algae zizityalo ezikhula emanzini. Zinokuba zincinci kangangokuba awukwazi ukuzibona ngeliso lenyama. Ezi zi-microalgae kuba unokuzibona kuphela phantsi kwe-microscope. I-Macroalgae, kwelinye icala, inokukhula ukuya kwiimitha ezingamashumi amathandathu ubude.
I-algae inokwahlulwa ibe yi-algae yasemanzini olwandle kunye ne-algae yasemanzini acocekileyo. Kodwa kukwakho nee<em>algae ezihamba emoyeni eziqwini zemithi okanye ematyeni nakwi<em>algae yomhlaba ehlala emhlabeni. Kwane-algae yekhephu ezintabeni okanye kwi-North Pole okanye kwi-South Pole.
Abaphandi baqikelela ukuba kukho malunga nama-400,000 eentlobo ezahlukeneyo ze-algae. Noko ke, bamalunga nama-30,000 XNUMX kuphela abaziwayo, okt nkqu nesishumi ngasinye. I-algae isondelelene kakhulu enye kwenye. Into abafana ngayo bonke kukuba banenucleus yeeseli nokuba banokuzenzela ukutya ngokukhanya kwelanga. Ukwenza oku, bavelisa ioksijini.
Kodwa kukho enye into ekhethekileyo, eyile algae eluhlaza okwesibhakabhaka. Abaphandi babecinga ukuba ezi zizityalo. Noko ke, namhlanje siyazi ukuba yintsholongwane. Ukuthetha ngokuthe ngqo, yiklasi ye-cyanobacteria. Ezinye iintlobo zithwala into ebanika umbala ozuba. Ngenxa yoko igama. Noko ke, ezi ntsholongwane zinokuvelisa ukutya neoksijini ngoncedo lokukhanya kwelanga, njengezityalo. Yiyo loo nto isabelo esingalunganga sasibonakala. Kwaye ngenxa yokuba ibisoloko injalo, i-algae eluhlaza okwesibhakabhaka-eluhlaza ngokuqhelekileyo isabalwa njenge-algae, nangona oku kungalunganga.
Igama lethu elithi alga livela kulwimi lwesiLatini kwaye lithetha ukhula lwaselwandle. Ngamanye amaxesha siyisebenzisela izilwanyana ezingezo algae ngokwenene, njenge-algae eluhlaza okwesibhakabhaka: zikhangeleka njenge-algae, kodwa ziyi-bacteria.
Yintoni ukusetyenziswa okanye ingozi ye-algae?
Rhoqo ngonyaka, iibhiliyoni zeetoni ze-algae ezincinci zikhula kwimilambo kunye neelwandle zehlabathi. Zibalulekile kuba zenza isiqingatha seoksijini esemoyeni. Banokukwenza oku nangaliphi na ixesha lonyaka, ngokungafaniyo nemithi yethu, engenamagqabi ebusika. Kwakhona zigcina icarbon dioxide eninzi yaye ngaloo ndlela zithintela ukutshintsha kwemozulu.
I-algae ekhula ngaphantsi kwamanzi iyinxalenye yeplankton. Izilwanyana ezininzi zihlala kulo, ngokomzekelo, iminenga, ookrebe, oononkala, iimbaza, kodwa kwaneesardadi, iiflamingo nezinye izilwanyana ezininzi. Noko ke, kukwakho ne<em>algae enetyhefu enokubulala iintlanzi okanye yenzakalise abantu.
Kwakhona abantu basebenzisa i-algae. E-Asiya, kudala kukutya okuthandwayo. Zityiwa zikrwada kwisaladi okanye ziphekwe njengemifuno. I-algae iqulethe izinto ezininzi ezinempilo ezifana neeminerali, amafutha okanye iicarbohydrates.
Noko ke, ubulembu obuthile bunokusetyenziselwa ukufumana imicu yelaphu, idayi ye-inki, izichumiso zezolimo, izinto ezityebisa ukutya, amayeza nezinye izinto ezininzi. I-algae iyakwazi nokuhluza isinyithi esinzima esinetyhefu kumanzi amdaka. I-algae ke ngoko ikhula ngokulinywa ngabantu.
Nangona kunjalo, i-algae inokwenza iikhaphethi ezixineneyo emanzini. Loo nto isusa umnqweno wokuqubha kwaye iihotele ezininzi eziselunxwemeni zilahlekelwa ngabathengi bazo kwaye zingafumani nto. Oonobangela sisichumiso elwandle kunye nokufudumala kwamanzi olwandle ngenxa yokutshintsha kwemozulu. Ezinye iintlobo ze-algae ziphindaphindeka ngokukhawuleza. Ezinye zivelisa iintyatyambo ezininzi ngakumbi, zijika amanzi abebomvu.
