Final answer:
The statement that all prokaryotes are single-cellular organisms while all eukaryotes are multicellular organisms is False. Prokaryotes, which include bacteria and archaea, are indeed predominantly single-celled, while eukaryotes can be either single-celled or multicellular, such as in animals, plants, and some protists.
Step-by-step explanation:
Comparison of Prokaryotic and Eukaryotic Cells
All prokaryotes are single-cellular organisms, which include the domains of Bacteria and Archaea. They are characterized by the lack of a membrane-bound nucleus and other membrane-bound organelles. Their DNA is not enclosed within a nucleus but is instead found within the cell’s cytoplasm. On the other hand, eukaryotes can be either single-celled or multicellular organisms, which include animal cells, plant cells, fungi, and protists. These cells possess a membrane-bound nucleus where the DNA is stored, and they also contain other membrane-bound organelles such as mitochondria.
The statement that "All prokaryotes are single-cellular organisms while all eukaryotes are multicellular organisms" is False. While prokaryotes are indeed predominantly single-celled, eukaryotes encompass a wide variety of organisms that can be either single-celled or multicellular. For instance, many protists are single-celled eukaryotes.
When comparing the two cell types, prokaryotic cells do not have mitochondria, which is True. Additionally, it is False to say that prokaryotic cells do not have DNA; they certainly do, but it is not compartmentalized within a nucleus. Addressing another misconception, it's False that all single-celled organisms are prokaryotes since some eukaryotes are also single-celled. Regarding the evolutionary timeline, prokaryotes were the first type of organism to evolve, which makes sense considering their simpler structure compared to eukaryotic cells.
