Ciliates contain two types of nuclei: somatic "macronucleus" and the germline "micronucleus". Only the DNA in the micronucleus is passed on during sexual reproduction (conjugation). On the other hand, only the DNA in the macronucleus is actively expressed and results in the phenotype of the organism. … Visa mer The ciliates are a group of alveolates characterized by the presence of hair-like organelles called cilia, which are identical in structure to eukaryotic flagella, but are in general shorter and present in much larger numbers, with a … Visa mer Nuclei Unlike most other eukaryotes, ciliates have two different sorts of nuclei: a tiny, diploid micronucleus (the … Visa mer Reproduction Ciliates reproduce asexually, by various kinds of fission.
