Answer:
A. prokaryotes have no nucleus.
Step-by-step explanation:
Eukaryotes cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in the cellular structure of prokaryotes and Eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes.
