<P> The word `` protoplasm '' comes from the Greek protos for first , and plasma for thing formed , and was originally used in religious contexts . It was used in 1839 by J.E. Purkinje for the material of the animal embryo . Later , in 1846 Hugo von Mohl redefined the term ( also named as Primordialschlauch , `` primordial utricle '' ) to refer to the `` tough , slimy , granular , semi-fluid '' substance within plant cells , to distinguish this from the cell wall and the cell sap ( Zellsaft ) within the vacuole . Thomas Huxley ( 1869 ) later referred to it as the `` physical basis of life '' and considered that the property of life resulted from the distribution of molecules within this substance . The protoplasm became an `` epistemic thing '' . Its composition , however , was mysterious and there was much controversy over what sort of substance it was . </P>
