Olee nke n'ime ihe ndị a na-esonụ na-abụghị ihe na-acha odo odo: phycobilins, thylakoids, ma ọ bụ cyanobacteria? N'iburu ajụjụ nke mbụ n'uche, dee ihe gbara ya gburugburu bụ́ nke ga-enye azịza ya. Ọ nwere ike ịbụ 1 - 20 ahịrịokwu. Ihe ndị gbara ya gburugburu:
A na-ewere cyanobacteria dị ka ndị nna ochie nke chloroplasts. Mgbe ụfọdụ, a na-akpọ ha ahịhịa ndụ na-acha anụnụ anụnụ n'agbanyeghị na ha bụ ndị na-eto eto. Ha bụ ụdị nje bacteria dị iche iche nwere ike ịrụ ọrụ photosynthesis, ha na-ejikwa gram-negative, nke pụtara na ha nwere mkpụrụ ndụ abụọ. Cyanobacteria nwekwara peptidoglycan cell wall, nke dị oke karịa na nje bacteria ndị ọzọ na-adịghị mma, nke dị n'etiti membran abụọ ha. Dị ka chloroplasts, ha nwere thylakoids n'ime. N'elu akpụkpọ ahụ thylakoid, e nwere pigmenti photosynthetic, gụnyere chlorophyll a. Phycobilins bụkwa ihe na-ahụkarị nke cyanobacterial pigments, nke a na-ahazi n'ime hemispherical phycobilisomes jikọtara na mpụga nke membranes thylakoid (ọ bụ ezie na ọ bụghị ihe niile chloroplasts na-ekerịta phycobilins).
