cytoplasm
Cytoplasm is one component of cells that is common to all cells. Cytoplasm is the gel-like material between the cell membrane and the nucleus. The cytoplasm plays an important role in a cell, serving as a "jelly" in which organelles are suspended and held together by the cell membrane. Though prokaryotic cells do not have organelles though they do have ribosomes , they still have cytoplasm. It is within the cytoplasm that most cellular activities occur, including the many metabolic pathways that occur within organelles, such as photosynthesis and aerobic respiration.
