Coenocyte, also known as syncytium, refers to a multicellular organism that contains several nuclei. Synonyms for the term coenocyte include multinucleated, multi-nucleate, syncytiotrophoblast, syncytium-inducing factor, and coenocytic. These terms are used interchangeably to describe the same biological phenomenon, where cells fuse together to form a large, multinucleated organism. The coenocyte is observed in various organisms, from plants to animals, and refers to the fusion of several cells that result in a single organism with multiple nuclei. This phenomenon is particularly common in fungi, where coenocytic mycelia are composed of fused hyphae that result in a single, multinucleated organism.
