Answer» Right choice is (a) GRANA, thylakoids To explain: The STROMA actually contains a number of grana made up of disc-like thylakoids. Grana and thylakoids are the main sites of light reaction. A stack of thylakoid discs together forms a GRANUM (plural of grana). Grana ranges from 10 to almost 100 in number.
