flagella
propel organelles through the cytoplasm.
can be used for movement of both prokaryotic and eukaryotic cells.
propel ribosomes through the cytoplasm.
can be found in eukaryotic cells but not prokaryotic cells.

Explanation:

Flagella are whip-like structures used for cellular movement. Prokaryotic cells (e.g., bacteria) and eukaryotic cells (e.g., sperm cells, some protists) both have flagella (though their structure differs). The other options are incorrect: organelles/ribosomes are moved by cytoplasmic streaming, not flagella, and flagella exist in both cell types.

Answer:

can be used for movement of both prokaryotic and eukaryotic cells.
