Definition: What is the Cytoplasm? In cell biology, the cytoplasm is a highly viscous (gel-like) substance enclosed within the cell membrane. It is composed of water (about 85 percent), proteins (10 to 15 percent), lipids (2 to 4 percent), nucleic acids, inorganic salts and polysaccharides in smaller amounts. Depending on the cell, cytoplasm may also contain occasional granules of inclusions (e.g. stored nutrients and pigments, etc). Apart from the cell membrane, which encloses all cell components, a majority of cell organelles ( ribosome , Golgi apparatus , Endoplasmic Reticulum , etc) are located in the cytoplasm. For this reason, most of the metabolic activities occur within the cytoplasm. * Organelles are also part of the cytoplasm. * The cytoplasm makes up nine-tenths of the entire cell.
