| The internal membranes are shaped like disks and are often stacked together, forming a granum. |
| Those appressed to another thylakoid in a stack called a granum are "appressed" or "agranal" thylakoids. |
| The Spanish name grana, confounded with granum, may have given rise to this contest. |
| The chloroplasts of some plants show the invagination of the inner membrane into granum particularly in Sorghum, maize and sugarcane. |
| The number of thylakoids per granum is influenced greatly by the irradiation intensity during development. |
