What are the functions of the macronucleus and one or more small micronuclei in Paramecium?
A) The macronucleus undergoes meiosis to produce haploid micronuclei that are exchanged in conjugation; this then produces a micronucleus for general cell housekeeping.
B) The micronucleus undergoes meiosis to produce haploid micronuclei that are exchanged in conjugation; the macronucleus is responsible for the "day-to-day" functions of the cell.
C) Diploid micronuclei control the cell and the haploid macronuclei are exchanged in conjugation for reproduction.
D) A micronucleus is always (1n) for conjugative reproduction, the macronucleus functions for general cell coding, and the two are otherwise unrelated.
E) None of the choices are correct.

The micronucleus in Paramecium functions in sexual reproduction by undergoing meiosis to produce haploid micronuclei that are exchanged in conjugation. The macronucleus is responsible for the day-to-day functions of the cell, such as gene expression and protein synthesis.
