Midkee ka mid ah waxyaabaha soo socda midab ma aha: phycobilins, thylakoids, ama cyanobacteria? Marka la eego su'aasha hore, ku qor macnaha guud ee jawaabta. Waxay noqon kartaa 1 ilaa 20 jumladood. Macnaha guud:
Cyanobacteria waxaa loo tixgeliyaa awoowayaasha chloroplasts. Mararka qaar waxaa loo yaqaannaa algae buluug-cagaaran inkastoo ay yihiin prokaryotes. Waxay yihiin noocyo kala duwan oo bakteeriyada ah oo awood u leh inay sameeyaan fotosintesis, waana gram-negative, taasoo la micno ah inay leeyihiin laba xuub oo unug. Cyanobacteria sidoo kale waxay ka kooban tahay derbiga unugyada peptidoglycan, kaas oo ka dhumuc weyn bakteeriyada kale ee gram-negative, oo ku yaal inta udhaxeysa labada xuub ee unugyada. Sida chloroplasts, waxay leeyihiin thylakoids gudaha ah. Xididdada thylakoid-ka waxaa ku jira midabada iftiiminta, oo ay ku jiraan chlorophyll a. Phycobilins sidoo kale waa midabada cyanobacterial caadiga ah, sida caadiga ah loo abaabulay phycobilisomes hemispherical ku lifaaqan dibadda ee xuubka thylakoid (phycobilins ma wadaagaan dhammaan chloroplasts in kastoo).
