Answer: It has a cell wall but lacks a well–defined nucleus and organelles, and its cytoplasm doesn't have much structure.
Step-by-step explanation:
The main characteristic of a prokaryotic cell is it is a microorganism that lacks of a defined nucleus, therefore it is said that it has no nucleus. This means the cell's genetic material is simpler than the others and is dispersed in the cytoplasm (in the nucleoid).
Due to having a less complex genetic information, prokaryotes are considered the first living organisms that existed on the planet and are mostly bacteria. In addition, these cells can feed themselves using organic matter and sunlight by photosynthesis or inorganic matter (autotrophic feeding) and can also feed on other organisms (heterotrophic feeding).
