Question

comparing prokaryotes and eukaryotes
prokaryotes = bacteria
pro = no nucleus

1. what four characteristics do all prokaryotes have in common?
2. what living organisms are prokaryotes?
3. what main structure is not in prokaryotes?

bacteria (prokaryotes) are unicellular and are covered by a cell wall. just within the cell wall is the cell membrane. bacteria are prokaryotes, they do not have a nucleus. they do have dna. the extra space in the cell is filled with a fluid called cytoplasm. floating throughout the cytoplasm are ribosomes. ribosomes make proteins for the cell.

1. what surrounds all prokaryotic cells?
2. what two structures are found inside the prokaryotic cell?
3. what do ribosomes make?
4. how many cells are all prokaryotic organisms?

Explanation:

1. The text indicates that all prokaryotes have DNA, ribosomes, a cell membrane, and a cell wall.
2. It states that bacteria are prokaryotes.
3. It mentions that prokaryotes do not have a nucleus.
4. The text says prokaryotic cells are surrounded by a cell wall and a cell - membrane.
5. Inside the prokaryotic cell, there are DNA and ribosomes.
6. It is stated that ribosomes make proteins.
