Definition of granum. plural. grana. play \ËgrÄ--nÉ\. : one of the lamellar stacks of chlorophyll-containing thylakoids found in plant chloroplasts.
As the name implies, chloroplast contains photosynthetic pigment called chlorophyll. Because of the presence of this pigment, chloroplasts can utilize light to synthesize ATP and sugars. Thus, the organisms with chloroplasts can produce their own food. Chloroplasts have two membranes, similar to mitochondria. In addition to these membranes, they have closed compartments called grana. Grana are found inside the inner membrane, and each granum is made up of few to several dish shaped structures called thylakoids. The chlorophyll is found on these thylakoids.
