ELAEOCYTE Meaning and
Definition
-
Elaeocyte is a term used in the field of biology to refer to a specific type of cell found in certain marine invertebrates, particularly in bivalves such as mussels or oysters. An elaeocyte is a specialized cell that is typically oval or round in shape and contains numerous lipid droplets within its cytoplasm. These lipid droplets are mainly composed of lipids, which include various fats or oils.
Elaeocytes are primarily responsible for storing and transporting lipids within the body of the organism. They play a crucial role in energy metabolism, as they serve as repositories for energy-rich lipids that can be utilized during periods of low food availability or high energy demands, such as reproduction or migration.
In addition to their role in lipid storage, elaeocytes also possess important immune functions. They are involved in the defense mechanisms of the organism by engulfing and removing foreign particles or pathogens from the tissues. Elaeocytes can also release certain substances that participate in immune responses, such as antimicrobial compounds or cytokines.
Overall, elaeocytes are considered key cells for both energy storage and immune defense in marine invertebrates. Their ability to efficiently store lipids and provide energy reserves allows these organisms to adapt to their fluctuating environments, while their immune functions contribute to the protection against pathogens or harmful substances.
Etymology of ELAEOCYTE
The word "elaeocyte" is derived from two different sources: the Greek word "elaia", meaning "olive", and the Greek word "kytos", meaning "cell". In biological terms, an elaeocyte refers to a type of cell found in certain invertebrates, particularly mollusks like snails and slugs. These cells are specialized to store or secrete lipids or oils, and their name reflects their characteristic resemblance to olives or oil droplets.
