Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Virus is an exception to cell theory as it lacks cell and protoplasm, the living substance in which all life processes take place. But it can reproduce in a living host cell, by using raw materials (nucleotides) and biosynthetic machinery (ribosomes, /RNA, enzymes) of the host cell.

Cell: The Unit of Life
- A cell is derived as the functional and structural unit of life. Every cell is surrounded by a cell membrane that dissects the external and internal environments of the cell. The interior environment of a cell is called the cytoplasm.
- It carries cellular machinery and structural elements. The nucleus is present in the center of the cell, which includes all the hereditary information of an organism. Some of the molecules present in the cell are protein, carbohydrates, starch, and sugar.
