Question

Define-

A. protoplasm

B. nucleoplasm

Answer 1

A)Protoplasm is the living content of a cell that is surrounded by a plasma membrane. It is a general term for the cytoplasm.Protoplasm is composed of a mixture of small molecules such as ions, amino acids, monosaccharides and water, and macromolecules such as nucleic acids, proteins, lipids and polysaccharides. In eukaryotes the protoplasm surrounding the cell nucleus is known as the cytoplasm and that inside the nucleus as the nucleoplasm. In prokaryotes the material inside the plasma membrane is the bacterial cytoplasm, while in Gram-negative bacteria the region outside the plasma membrane but inside the outer membrane is the periplasm.
B)Similar to the cytoplasm of a cell, the nucleus contains nucleoplasm, karyoplasm, or nucleus sap. The nucleoplasm is one of the types of protoplasm, and it is enveloped by the nuclear membrane (also known as the nuclear envelope). The nucleoplasm includes the chromosomes and nucleolus.
