<prompt> Siyini isihloko esiyinhloko sesigaba? Njengoba kunikezwe umbuzo odlule, bhala umongo onempendulo yawo. Kungaba imisho engu-1 kuya kwengu-20. Umongo:  <response>: Kunemibono ethile eyiphutha evamile ngezindwangu zangaphandle nezangaphakathi ze - chloroplast. Iqiniso lokuthi ama-chloroplast azungezwe ulwelwesi oluphindwe kabili livame ukucashunwa njengobufakazi bokuthi ayizinzalo zama-cyanobacteria angena ngaphakathi. Lokhu kuvame ukuhunyushwa njengokusho ukuthi ulwelwesi lwangaphandle lwe-chloroplast luwumkhiqizo we-membrane yeselula yomgcini ehlanganiswa ukuze kwakheke i-vesicle ezungeze i-ancestral cyanobacteriumokungelona iqinisokokubili ulwelwesi lwe-chloroplast lufana nolwelwesi lwe-cyanobacterium lwangempela.
