The following drawing is ment to represent a eucaryotic cell. Every cell (procaryotic or eucaryotic) is bounded by a plasma membrane. In addition, eucaryotic cells have many intracellular membranes that define functional areas of the cell. Since many of these intracellular membrane bounded structures carry out very specific functions for the cell, just as a body has organs that carry out specific functions, they are called organelles.
The picture below is yet another representation of a cell.
