What is one defining feature of a prokaryotic cell?

cytoplasm surrounds organelles

organelles are not membrane-bound

membrane-bound organelles

have a cell wall outside plasma membrane

The correct answer is "organelles are not membrane-bound ".

Explanation:

All the organisms possess a cell membrane that gives protection and a selective barrier to allow the exchange of nutrients between the cells and the environment. However, one characteristic that defines a prokaryotic cell is that their organelles are not membrane-bound. The prokaryotic cell possess cytoplasm and ribosomes as organelles to make the cell's function, and almost all of the them have a cell wall that gives support and protection.
