It is the general mass of nucleus. 6 * The nuclear envelope *Components: Eukaryotic Nucleus - Structure . Essentially, the plasma membrane refers to the cell membrane that defines the boundaries of a cell (and cell organelles). Many cellular processes also occur in the cytoplasm, such as protein synthesis, the first stage of cellular respiration (known as glycolysis), mitosis, and meiosis.
