So I do not believe it is possible for a multicellular organism to exist with no cell differentiation. However, if you do further research and discover otherwise, then I would be happy to be proven wrong. I hope this helped!

WebCell-cell signaling involves the transmission of a signal from a sending cell to a receiving cell. However, not all sending and receiving cells are next-door neighbors, nor do all cell pairs exchange signals in the same way. There … WebAnswer: Euglena is neither a plant nor an animal, but a single cell flagellate eukaryotic organism — with some characteristics of both plants and animals — that belongs to “kingdom” Protista. Since it is a unicellular organism with some plant and animal characteristics, it is called a protist. Plant cells have walls. how many ccs can a bladder hold
