Answer 1

Hint: He is best known for his discovery of large nerve cells with many branching extensions of the brain and fibrous tissue cortex, which lead the pacemaker's stimulation to all areas of the heart via the internal walls of the ventricles.

Complete Answer:
- Protoplasm is the cell's living component, containing various cellular organelles. It has a jelly, colourless, transparent and viscous living substance found within the cell wall.
- The word protoplasm was proposed in 1835 and is considered as the primary material, since it encompasses different phases of life. Cell was considered to be a protoplasm container.
- Nevertheless, the idea could not clarify the origin of cell structures, mainly the nucleus. The cytoplasm is the initial protoplasm, present in a eukaryotic cell among the cell membrane and the cell nucleus. A cytoplasm plays an essential part in the cell's protection, cell form and storage of the organelle substances.
- The nucleus is the second portion of the protoplasm that stores an organism's genetic material. The protoplasm contains fats, proteins, hormones, enzymes. These can be dissolved or suspended in the protoplasm's water portion.
- In 1940, Johannes Purkinje first named Protoplasm. The name was used by Prague's Johannes Purkinje who researched plant cell contents. This living cell substance, which came from the ancient liturgy of the Christian church, was called protoplasm by Purkinje.

Thus, the correct answer is option A. i.e., Johannes Purkinje.

Note: The word protoplasm was proposed in 1835 and is considered as the primary material, since it encompasses different phases of life. Cell was considered to be a protoplasm container. Protoplasm is a mixture of molecules including proteins, polysaccharides, lipids, monosaccharides, amino-acid, etc.
