cytoplasm

Cytoplasm is a homogeneous, generally clear jelly-like material that fills cells. The cytoplasm consists of cytosol and the cellular organelles, except the nucleus. The cytosol is made up of water, salts and organic molecules and many enzymes that catalyze reactions. The cytoplasm plays an important role in a cell, serving as a "molecular soup" in which the organelles are suspended and held together by a fatty membrane. It is found within the plasma membrane of a cell and surrounds the nuclear envelope and the cytoplasmic organelles. The cytoplasm plays a mechanical role to maintain the shape, the consistency of the cell, and to provide suspension to the organelles. It is also a storage place for chemical substances indispensable to life. Vital metabolic reactions take place here, for example anaerobic glycolysis and protein synthesis.
