Cytoplasm
The cell compartment bounded by the plasma membrane (cell membrane). It is a complex, organised and dynamic environment.
The biochemical reactions of cellular metabolism occur constantly to ensure the permanent renewal of molecular and cellular constituents. It also contains a large number of organelles that each performs a specific function. It surrounds the cell nucleus in the centre. Cytoplasm is the medium essential for synthesis, the multiplication of genes (nucleus) and then their transformation into RNA and proteins (cytoplasm).
