Ciliates contain a variety of organelles plus two kinds of nuclei. The larger type of nucleus, the macronucleus, contains a great deal more DNA than the smaller nucleus, the micronucleus.

∙ 10y agoMost ciliates have two nuclei: a macronucleus that contains hundreds of copies of the genome and controls metabolisms, and a single small micronucleus that contains a single copy of the genome and functions in sexual reproduction.

∙ 12y agoThe paramecium has two nuclei, a big and small one. The big one operates as the director of the cell's activities, rather like a little brain. The smaller one is used for reproduction.

∙ 14y agoThere are two nuclei because they both do different things. The macronucleus controls the paramecium's metabolism. The micronucleus controls reproduction.

What is nuclear dimorphism?
Observed in protozoa ciliates, this term refers to the characteristic of having two kinds of nuclei in one cell which each have differing genetic functions.
Are Ciliates autotrophic or heterotrophic?
ciliates are heterotrophs
What photosynthetic protists have glassy two part cell wall made of silica?
diatoms
Are ciliates helpful?
Yes.
How do ciliates deal with osmosis?
Some ciliates, like the paramecium, have contractile vacuoles that fill with water and then expel the water when they get full.
What have two nuclei what are their names and functions?
Most ciliates have two nuclei: a macronucleus that contains hundreds of copies of the genome and controls metabolisms, and a single small micronucleus that contains a single copy of the genome and functions in sexual reproduction.
What is nuclear dimorphism?
Observed in protozoa ciliates, this term refers to the characteristic of having two kinds of nuclei in one cell which each have differing genetic functions.
How does actinosphaerium eat?
Actinosphaerium are 200 to 1000 μm in diameter, with many nuclei, and are found only in freshwater. They eat small flagellates, diminutive ciliates, and microscopic algae.
How do you ciliates eat?
Ciliates eat with their vacuole.
Are Ciliates autotrophic or heterotrophic?
ciliates are heterotrophs
Are pollen grains haploid or diploid if they have two nuclei the generative and the tube nuclei?
Pollen grains with generative and tube nuclei have two haploid nuclei.
A sentence with the word nuclei?
Paramecium has two nuclei.
What is a good sentence for nuclei?
Some protists have two nuclei.
Are amoebas ciliates?
No. Amoeba and ciliates are two groups of protozoan parasites. The amoeba are unicellular, which are characterized by the pseudopodia. Ciliates are protozoa, unicellular and use cilia on their surface.
How can a unicellular cell be known as eukaryotic Under what circumstances Eukaryotes are multi cellular organisms so what makes certain unicellular organisms eukaryotic?
The cellularization theory states that a unicellular organism would have developed from membrane boundaries/partitions around each nuclei from a single celled organism with multiple nuclei. Protists like ciliates and slime molds have multiple nuclei supporting this theory.
The two daughter nuclei are formed during?
During the telophase stage of mitosis and meiosis two daughter nuclei are formed. The daughter nuclei begin forming the two ends of the cell.
Does ciliates cause malaria?
The ciliates do not cause malaria. Malaria is caused by protozoa. They have pseudopodia.
