No, their sizes are not 50S and 30S, but vary greatly. Yes, mitochondria and plastids have 70S-like ribosomes, rather than 80S-like ribosomes, but these have evolved considerably from their eubacterial precursors. Compared to their prokaryotic homologs, many of the eukaryotic ribosomal proteins are enlarged by insertions or extensions to the conserved core. Furthermore, several additional proteins are found in the small and large subunits of eukaryotic ribosomes, which do not have prokaryotic homologs.
