In which of the animal dimorphic nucleus is found : -Ciliate protozoans such as Paramecium have two different kinds of nuclei (nuclear dimorphism).
The large macronucleus (vegetative nucleus) controls the everyday metabolic activities of the cell.
The small micronucleus (reproductive nucleus) takes part in sexual reproduction (conjugation).
Amoeba, Trypanosoma and Plasmodium have only one kind of nucleus.
So a dimorphic nucleus is found in Paramecium caudatum.
