Where are the thylakoids and Granum found?

The chloroplast contains chlorophyll within its thylakoids, which absorbs light energy and gives chloroplasts its green color. Stacks of thylakoids are known as grana, which exist in the open space of the chloroplast known as the stroma. read more

A granum (plural grana) is a stack of thylakoid discs. Chloroplasts can have from 10 to 100 grana. Grana are connected by stroma thylakoids, also called intergranal thylakoids or lamellae. Grana thylakoids and stroma thylakoids can be distinguished by their different protein composition. read more

Each granum has 2-100 thylakoids. Because of presence of grana, thylakoids are differentiated into 2- granal thylakoid and stroma or intergranal thylakoids. The membranes of thylakoid possess chlorophylls and carotenoids. read more
