In eukaryotes, tRNA molecules are synthesized by RNA polymerase III, which is specialized for transcribing small RNA molecules, including 5S rRNA and tRNAs. RNA polymerase I transcribes most rRNA (except 5S rRNA), and RNA polymerase II synthesizes mRNA and some snRNAs. Ribosomes, on the other hand, are involved in translation and not RNA synthesis.
