ANSWER
A nucleus in eukaryotic cells is a specialized double membrane-bound protoplasmic body which contains all the genetic information for controlling cellular metabolism and transmission to the posterity. Whereas in prokaryotic cell, it is not bounded by membrane
The cell wall is the outer rigid protective, a supportive and semitransparent covering of plant cells, fungi and some protists. The cell wall is absent in animal cells.
In prokaryotic cells, membrane-bound cell organelles are absent so that there is a single membrane that surrounds the cell. Hence, prokaryotes have a single membrane or one-envelope system.
Each cell is made up of a small mass of protoplasm containing a nucleus in its inside and a plasma membrane with or without a cell wall on its outside. The cell is made up of biotic materials.
So, the correct answer is option C.
