<prompt> Iziphi izindawo ezivame kakhulu ukuba nama-stromules? Njengoba kunikezwe umbuzo odlule, bhala umongo onempendulo yawo. Kungaba imisho engu-1 kuya kwengu-20. Umongo:  <response>: Ngezinye izikhathi ulwelwesi lwama - chloroplast luye lujule luye kuyi - cytoplasm, lube i - stromule, noma i - tubule equkethe i - stroma. Ama-stromules awavamile kakhulu kuma-chloroplast, futhi avame kakhulu kwamanye ama-plastide afana nama-chromoplast nama-amyloplast emaqabungeni nasezimpande, ngokulandelana. Zingase zibe khona ukuze zikhulise indawo ye-chloroplast yokuthuthwa kwe-cross-membrane, ngoba zivame ukuhlukaniswa futhi zihlanganiswe ne-endoplasmic reticulum. Lapho ziqala ukubonwa ngo-1962, ezinye izazi zezinto eziphilayo zezitshalo zazikubheka njengokwakhiwe, zithi ama-stromules ayengama-chloroplast anesimo esingajwayelekile anezifunda ezicinene noma ama-chloroplast ahlukanisayo. Nokho, kunobufakazi obandayo bokuthi ama-stromules ayasebenza, ayizici eziyingxenye yama-plastide amangqamuzana ezitshalo, hhayi nje izinto zokwenziwa.
