Question

‘’Protoplasm is physical basis of life’’ was said by
A. Huxley
B. Purkinje
C. Lamarck
D. Hooke

Answer 1

Hint: Protoplasma is surrounded by the plasma membrane and is the living part of the cell. Protoplasm is a Greek word, coined by the J.E.Purkinje in \[1839\] .

Complete step by step answer: In Greek, protos means for first and plasma means for things formed. In $1839$ , it was used by J.E.Purkinje for the material of animal embryos. Later, in $1846$, Hugo von Mohl redefined the terms he said, it is the slimy, semi-fluid, tough, granular substance to distinguish between the cell wall and cell sap within the vacuole of a plant cell. Thomas Huxley in $1869$, said protoplasm is the physical basis of life. The term ‘bioplasma’ was created by Beale in $1872$. The protoplasm was proposed by Hanstein in $1880$, as the entire cell except for the cell wall.
From the history of discovery of protoplasm, we can say the ‘’Protoplasm is the physical basis of life’’ was said by Huxley. Hence, the correct answer is option A.
So, the correct answer is “Option A”.

Note: The protoplasm is composed of carbohydrates, proteins, nucleic acid, lipids and inorganic salts. It is a fluid or jelly-like substance consisting of cytoplasm and nucleoplasm. Since the prokaryotic organisms do not have a distinct nucleus and other cytoplasmic cell organelles, therefore, the protoplasm refers to the material present inside the cell membrane. In the case of gram-negative bacteria, the protoplasm extends between the cytoplasmic region and outer membrane called the periplasmic region.
