<u>Explanation</u>:
- The prokaryotic cells are present in unicellular organisms such as bacteria and lack Nucleus in it. The cell X is not filled with x-mark in the nucleus.
- The prokaryotic cells consist of the cell membrane, cell wall and a genetic material composed of DNA. All these are marked with x-mark for cell X.
- Chloroplasts are not present in prokaryotic cells and the space for it is left blank in cell X without the x-mark.
- This information clearly shows that prokaryotic cell structure is viewed likely in cell X.
