Cellular differentiation: is the process of cells becoming specialized as the body develops. Produces the specialized cells that form the tissues of the body. Plasma membrane: separates the cell contents, or cytoplasm, from the extracellular fluid. Cytoplasm: the material located between the plasma membrane and membrane surrounding the nucleus. Organelles: intracellular structures suspended within the cytosol with specific functions. Nonmembranous organelles: not completely enclosed by membranes, and all of their components are in direct contact with the cytosol. Membranous organelles: isolated from the cytosol by phospholipid membranes. Breakdown or org compounds, neutralization of toxic compounds. Breakdown of org compounds and damaged organelles or pathogens. A fluid nucleoplasm surrounded by a double membrane. Controls metabolism, stores and processes genetic info, controls protein synthesis.
