In which of the following organisms would glycogen be stored?

Glycogen is a type of carbohydrate that is used as an energy source and stored in the liver and muscles of animals. Therefore, the organism that would store glycogen is the Rattus, which is a type of rodent commonly known as a rat. The other options, Spirogyra and Chlamydomonas, are both types of algae and do not have the ability to store glycogen. Magnifera, on the other hand, is the scientific name for mango, which is a fruit and not an organism that would store glycogen.
