Having a nucleus is the characteristics which defines a cell as a eukaryote. Option (c) is correct.
A prokaryotic cell is a straightforward, one-celled (unicellular) organism that is devoid of a nucleus or any other organelle that is membrane-bound. Soon, it will become clear that this is very different in eukaryotes. The nucleoid, a dark area in the center of the cell, is where prokaryotic DNA is located.
Bacteria, unlike Archaea and eukaryotes, have a polysaccharide capsule and a peptidoglycan cell wall formed of sugars and amino acids. The cell wall serves as an additional layer of defense, aids in maintaining the cell's form, and stops dehydration. The cell can adhere to surfaces in its environment thanks to the capsule. Fimbriae, pili, or flagella are present in several prokaryotes. While the majority of pili are employed to exchange genetic material, flagella are used for movement.
