What organisms are in Ciliophora?
(Phylum Ciliophora, Class Spirotichea) infest several genera of animals including gastropods with and without shells (limpets and sea hares) as well as seahorses, corals, clams, and others.
What is Ciliophora in biology?
Ciliophora (phylum Protozoa) A subphylum of protozoa in which cilia are present during at least one stage of the life cycle and in which two different types of nucleus (macronucleus and micronucleus) are normally present. Cells reproduce by binary fission. Sexual processes occur.
What is the function of Ciliophora?
Ciliophora are multinucleate organisms. The macronucleus controls cell functions and asexual reproduction. The micronucleus is also involved with sexual reproduction. Ciliophora are heterotrophic organisms.
How many species are there in the phylum Ciliophora?
Also known as ciliated protozoans, the phylum Ciliophora consists of single-celled organisms within the subkingdom Protozoa that move by means of cilia. Currently, there are over 7,500 described species within the group.
What are the characteristics of ciliates?
All ciliates share two features: a coating of cilia on their cell surfaces and two types of nuclei within single cells. The two nuclei types in each ciliate cytoplasm are different sizes; they are called the micronucleus and the macronucleus.
What are 3 facts about ciliates?
Ciliates are the largest (c.8,000 species) and the most complex of the Protozoans. They are found in both aquatic and terrestrial habitats and many are carnivorous. Ciliates have two nuclei (macronucleus and micronucleus) and a variety of organelles, such as a cystome (mouth).

What is Ciliophora conjugation?
Conjugation. Overview. Ciliate conjugation is a sexual phenomenon that results in genetic recombination and nuclear reorganization within the cell. During conjugation, two ciliates of a compatible mating type form a bridge between their cytoplasms.
What is ciliate in parasitology?
The ciliates are a group of protozoans 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 different undulating pattern than flagella.
What is ciliate conjugation?
Conjugation is often induced by lack of food. Two ciliates of opposite mating types come close together and form a cytoplasmic bridge between the two cells; the micromuclei divide by meiosis, the macronuclei disintegrate, and the conjugating cells exchange haploid micronuclei over the cytoplasmic connection.
