No matter what is the function of a particular cell organelle; all the cell organelles are made up of more or less similar molecules. All the molecules come together in a particular fashion to build up a particular cell organelle. It is similar to the same brick making a small house or a big mansion of a factory. The constituents remain the same but the function and purpose of the finished product changes. Hence, properties of cell organelles
are not always found in the molecular constituents of cell organelles.
