The cytoplasm or protoplasm is the portion of the cell that lies within the cytoplasmic membrane. The cytoplasmic matrix is defined as substances within the plasma membrane, excluding the genetic material. It is relatively featureless by electron microscope - although small granules can be seen. However, the cytoplasm carries out very important functions for the cell.
The cytoplasm holds many cellular constituents, including the cell pool (above). It is within the cytoplasm that many of the functions for cell growth, metabolism and replication are carried out.
