Cilia help move food into sitostoma. The food collected in sitostoma will continue to sitofaring. Once full, the food will go to the cytoplasm by forming a food vacuole. Tues ciliate has two nuclei: makronucle and mikronuclei. Makronukleus has a vegetative function. Micronucleus has a reproductive function, ie konjugasiContoh of ciliate is Balantidium coli, Vorticella and Paramecium.

Ciliate classHaving the 2 core cell (nucleus), which makronukleus (large nuclei), which controls the functions of daily life in a way to synthesize RNA, was also instrumental in asexual reproduction, and the micronucleus (small nuclei) that are exchanged during conjugation to the process of sexual reproduction. There contractile vacuoles that function to maintain water balance in her body. Many live in seawater and freshwater. Example: Paramaecium caudatum, Stentor, Didinium, Vorticella, Balantidium coli. The tool motion in the form of vibrating hair (cilia). Ciliate has several characteristics, among others:

a. Body Structure1. 

    1. Most symmetrical except ciliate ciliate primitiv, radial symmetry.

    2. His body was reinforced by perikel, the outer layers are composed by dense cytoplasm

    3. His body was covered with cilia, which envelops the entire main body called cilia somatic

    4. Ciliate has two types of cell nuclei (nucleus), which makronukleus the micronucleus.

    5. Ciliate has no special structure of air exchange and secretion of nutrients andhow to eatCiliate sitosom 

        has an open mouth or a short channel. In sitofaring primitiv in animals, is located at the mouth of the 

        interior but in most ciliate, they are replaced by the posterior. 

There are two kinds of mouth on the ciliate are:

1. Mouth wavy membrane: a ciliate which converge in a long line

2. Membrane in the form of short rows of cilia are united to form the discCiliate at the mouth function is to 

    produce food and push food particles into sitofaring. 

Examples of such well-known member of the ciliate Paramecium.

1. Stentor; Form as horns and settle in stagnant fresh water or flow. Pet food is a smaller ciliate.

2. Didinium; predators in aquatic ecosystems is that predators Paramecium.

3. Vortisella; shape like a bell, a long-stemmed with straight or spiral shape which has cilia around the 

    mouth. Live in fresh water, clinging to the stalk is contractile stem the substrate. Makananya form of 

    bacteria or leftover organic material that goes with the flow of water through the crack mouth.

4. Styllonichia; Shaped like a snail, cilia flocking

5. Ballanthidium coli; habitat in the human colon or large intestine and the ascending part of the transcendent 

    that can cause disturbances in the stomach.
