yes! the liver has many glycogen granuels
No, they do not. Only animal cells have glycogen granule to store energy.
The major storage form of energy in animals is glycogen ,it is stored in glycogen granule . Therefore glycogen granules in muscle cell act as stores of energy , since muscle cells requires alot of energy to perform their functions.

Just one salt granule can be irritating if you lie on it in bed.
Granule
glycogen
Glycogen is the molecule that function as the secondary long term energy storage in animal and fungal cells.It is made primarily by the liver and the muscles ,but can also be made by glycogenesis within the brain and stomach. The structure of gycogen consist of a core protein of glycogenin(a enzyme involved in converting glucose to glycogen,act as a primer, by polymerizing the first few glucose molecules, after other enzymes takes over) surrounded by branches of glucose units.The entire granule may contain approximately 30,000 glucose units.

granule
The size of a typical granule seen in the photosphere is about 1000 km across.
Each sugar granule has the mass (space) the granule occupies. Collectively, when in a 2kg bag of sugar, the mass is more obvious. Obviously, it would be difficult to measure a single granule (but not impossible).
