Final answer:
Cytoplasm, cell membrane, genetic material, and ribosomes are common to all prokaryotic and eukaryotic cells. The cell wall is not found in all eukaryotic cells. Ribosomes are the sites of protein synthesis in both cell types.
Step-by-step explanation:
The components that are found in ALL prokaryotic and eukaryotic cells are cytoplasm, cell membrane, genetic material (DNA/RNA), and ribosomes. While both cell types have these features, there are some differences. For instance, the cell wall is typically present in most prokaryotic cells and some eukaryotic cells, but it's not a universal feature across all eukaryotes. Meanwhile, ribosomes are the sites of protein synthesis and are present in both prokaryotic and eukaryotic cells. These ribosomes are crucial for the production of proteins based on the instructions encoded in the cell's genetic material. It's also important to note that the genetic material (DNA) in prokaryotes is located in a nucleoid region, whereas in eukaryotes, it is enclosed within a nucleus.
