Which feature is found in all cells? plasma membrane composed of phospholipids Compared with a eukaryotic cell, a prokaryotic cell lacks organelles beyond ribosomes. Without receptor proteins, a cell would not be able to bind to signal proteins from other parts of the body. Without tight junctions in certain tissues, fluids may leak out past the barrier the junction would create. Where do the vesicles that are being made for secretion from the cell become modified...
