Inclusions

Inclusions (/ɪnˈkluːʒənz/), from the Latin inclusio meaning "a shutting in", are non-living substances, such as stored nutrients or cell products, that are found inside cells. They are distinct from other cellular components as they are not bound by a membrane and are not directly involved in metabolism.

Types of Inclusions

There are several types of inclusions, including:

  • Lipofuscin - A type of inclusion that is a result of the wear and tear of the cell. It is often referred to as "wear and tear pigment".
  • Glycogen - A multi-branched polysaccharide of glucose that serves as a form of energy storage in animals, fungi, and bacteria.
  • Lipid Droplets - These are lipid-rich cellular organelles that regulate the storage and hydrolysis of neutral lipids.

Function

Inclusions serve as storage areas for nutrients and other substances within the cell. They are not active in the cell's metabolism and are not considered to be organelles.
