A
macronucleus is the larger type of
nucleus in ciliates. Macronuclei are
polyploid and undergo direct
division without mitosis. It controls the non-reproductive
cell functions, the everyday tasks, such as metabolism. During conjugation, the
macronucleus disintegrates, and a new
macronucleus is formed by karyogamy of the micronuclei. The
macronucleus...

nucleus believed to influence many
cell activities. It occurs in suctorian and ciliate protozoans (e.g., Paramecium). The
macronucleus is associated with one or more smaller micronuclei, which are necessary for
conjugation and
autogamy (reproduction by exchange between the nuclei of different individuals and of the same individuals,...
