Who is the father of protoplasm?
Protoplasm was first discovered by Dujardin, in the year 1835 and named as “sarcode” and then the protoplasm name was given by J.E. Purkinje,in the year 1839.
Who gave the theory of protoplasm?
Max Schultze established similarity between protoplasm and sarcode that leads him to propose a theory which is called as the protoplasmic theory by Hertwig. This theory states that protoplasm is the physical basis of life.
Who discovered cell nucleus and protoplasm?
Robert Brown
Answer: In 1831, Robert Brown discovered the nucleus in the cell. The nucleus in eukaryotic cells is a protoplasmic body covered by a double membrane that contains hereditary details. Robert Brown discovered the nucleus in 1831.

Who coined the term protoplasm Virchow?
It was coined by J.E. Purkinje in 1846 to address the material which makes up an animal embryo. Later, many scientists redefined it as “a substance within a plant cell” and “physical basis of life”. Thus, the term protoplasm was coined by (B) Purkinje.
What is protoplasm and who coined this term?
The fluid substance of the cell in which all the organelles of the cell reside and which is surrounded by the cell membrane is called as the proptoplasm of the cell. The term ‘protoplasm’ was first coined by Purkinje in 1839.

When did Max Schultze come up with the theory of protoplasm?
Max Schultze in 1861 proposed the “Protoplasm Doctrine” which states that all living cells are made of a living substance called Protoplasm. 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.
When did Hugo von Mohl invent the term protoplasm?
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.
How is the composition of protoplasm inconsistent and continuous?
The composition of protoplasm is inconsistent and continuous changes take place in it. It provides place where all life functions occur. The cells respond to various stimuli like temperature, light, chemicals, gravitation, pricking, electric shocks and others because of properties of protoplasm.
