| Chloroplasts at the proximal end of the cell also have grana, but with up to nine thylakoids per stack. |
| The thylakoid system was normally developed with grana composed of, on average, three to four stacked thylakoids. |
| The relative amount of stroma thylakoids is also increased, while the portion of grana thylakoids is lowered. |
| The pigment proteolipids of thylakoids have both a photosynthetic function and a role in membrane structure. |
| The number of thylakoids per granum is influenced greatly by the irradiation intensity during development. |
| Those appressed to another thylakoid in a stack called a granum are "appressed" or "agranal" thylakoids. |
