one of the permanent components of animal and plant cells. Each organoid performs specific functions that are vital for cell survival. Thus, any cell activity is a consequence of the coordinated operation of interconnected components, particularly organoids. Organoids include mitochondria, the Golgi apparatus, the centrosomes, the endoplasmic reticulum, ribosomes, and cytoplasmic microtubules. Organoids in plant cells include plastids and spherosomes. The classification of lysosomes as organoids is controversial. The term “organoid” derives from the similarity of these cell components to the organs of a multicellular organism. Organoids are contrasted to temporary cell inclusions, which appear and disappear in the metabolic process.
