Answer: In 1835 scientist Dujardin introduced us to the substance that was later on named protoplasm; he originally referred it to as “sarcode”. In 1839, J.E. Purkinje actually coined the term – ‘protoplasm’.
It was J.S. Huxley who called protoplasm to be the fundamental component of life in 1868. Finally in 1892 O. Hertwig came up with the ‘Protoplasmic Theory”.
Protoplasm is nothing but a colorless material that includes each living component in living organisms.
