Wanne daga cikin wadannan ya fi yawa a cikin tushen, chromoplasts ko amyloplasts? Bisa ga tambayar da ta gabata, ka rubuta mahallin da ke ɗauke da amsar. Zai iya zama jumla 1 - 20. Abubuwan da ke ciki:
Membranes na chloroplast wani lokacin yakan fito cikin cytoplasm, yana samar da stromule, ko tubule mai dauke da stroma. Stromules suna da wuya a cikin chloroplasts, kuma sun fi yawa a cikin wasu plastids kamar chromoplasts da amyloplasts a cikin petals da tushen, bi da bi. Suna iya wanzuwa don ƙara yawan farfajiyar chloroplast don jigilar ƙetare-membrane, saboda galibi suna da rassa kuma suna haɗuwa da reticulum na endoplasmic. Lokacin da aka fara lura da su a cikin 1962, wasu masanan kimiyyar halittu sun watsar da tsarin a matsayin na wucin gadi, suna da'awar cewa stromules kawai chloroplasts ne masu ban mamaki tare da yankuna masu ƙuntatawa ko rarraba chloroplasts.
