👉 ACalephoid is a biological structure characterized by a group of cytoplasmic cells arranged in a compacted pattern within a membrane-bound organelle called a vacuole. The term was coined by Georges Cahen in 1904 from the Greek root "ac" meaning 'a' and "lephos" meaning 'vacuum'. This structure is involved in various cellular functions such as signal transduction, protein synthesis and regulation of gene expression.
