  • Protoplasm JAMA
    Fundamental material composing all living things. Protoplasm, which exists in all plants and animals in the small units called cells, is mainly (85% to 90%) water and also contains proteins, fatty substances, and inorganic salts. It is always enclosed by a thin surface membrane that controls the passage of materials into and out of the cell. It displays the general properties associated with life--the capacity to respond to stimuli and the ability to perform the essential physiological functions.
