Question

Protoplasm is formed of -
a. O, P, Minerals
b. H, C, Iron
c. O, N, Iron
d. O, C, H, N

Answer 1

In prokaryotes, the matter inside the plasma membrane is called bacterial cytoplasm, while in Gram-negative bacteria the section outside the plasma membrane but inside the external membrane is the periplasm. Inside eukaryotes, the protoplasm enclosing the cell nucleus is known as the cytoplasm and that inside the nucleus as the nucleoplasm.

Complete answer:
The cellular fluid present within the nucleus is known as the nucleoplasm. The cellular liquid present amid the nuclear membrane and the cell membrane is known as cytoplasm. The arrangement of cytoplasm and nucleoplasm is known as protoplasm.

So basically, protoplasm is the living part of a cell that is enfolded by a plasma membrane. Protoplasm was believed to be present in two types: a liquid-like sol state or a jelly-like gel state.

These are composed of proteins that come together and fuse with glucose to form glycoproteins, fats to form lipoproteins, and nucleic acids to form nucleoproteins. Proteins present in the cytoplasm have carbon, hydrogen, nitrogen, and oxygen.

Hence, the correct answer is option (D).

Note: In eukaryotes, the protoplasm consists of two most important distributions: the cytoplasm and the nucleoplasm. The cytoplasm is the gelatinous material of the eukaryotic cell. It is composed of the cytosol, the vesicles, the cytoskeleton, the inclusions, and the organelles apart from the nucleus. As a result, the cytoplasm of a eukaryotic cell is the part of the cell which is between the cell membrane and the nuclear envelope. The material enclosed inside the nuclear envelope is called the nucleoplasm.
