What are the functions of the micro nucleus and the macro nucleus in paramecium

The micronucleus of paramecium is used for reproduction. The macronucleus of paramecium is used for transcription of genes, but the micronucleus is transcriptionally silent. The micronucleus undergoes meiosis prior to conjugation events, and it fuses with another haploid micronucleus from another cell to form a new paramecium cell. Micronuclei direct the formation of the macronuclei.

Answer: The micronucleus regulates reproduction and the macronucleus regulates the vegetative functions in paramecium.
