    The functionality of LUCA as well as evidence for the early evolution membrane-dependent biological systems together suggest that LUCA had cellularity and cell membranes. [23] As for the cell's gross structure, it contained a water-based cytoplasm effectively enclosed by a lipid bilayer membrane; it was capable of reproducing by cell division. [15]
