What is an example of a protozoa in a mutualistic relationship?
144305
There are several protozoans that participate in mutualistic symbiosis with animals, they mostly reside in the gut. For example, termites would not be able to digest wood if protozoans did not live in their gut. As a matter of fact, 33-50% of a termite's biomass is protozoans or bacteria. \nCorals are highly dependent on their photosythetic symbionts (dinoflagellates).\n\nyou can read more examples at http://azolla.fc.ul.pt/aulas/Estagios/Docs/MutualisticSymbioses.pdf#search='protozoan%20mutualistic%20symbiosis' \njust scroll down to the section on protozoans.\nmore info at http://www.101science.com/Symbiosis.htm\nhope this helps!

Kingdom-   Protozoa     \nPhylum-    Ciliophora     \nClass-     Ciliatea     \nSubclass-  Peritricha     \nOrder-     Peritrichida     \nSuborder-  Sessilina     \nFamily-    Vorticellidae     \nGenus-     Vorticella  \n\nhope that helps! Then there are different species such as campanula, citrina, comunis etc.

All organisms have symbiotic relationships. \n\nIn the case of sea horses the most obvious example are the bacteria that live in the gut. Without them the fish becomes much so prone to infection thatit can not survive. And of course the bacteria find the food provided essential to their survival.

1. Kingdom Monera [10,000 species]: Unicellular and colonial--including the true bacteria (eubacteria) and cyanobacteria (blue-green algae).\n\n2. Kingdom Protista (Protoctista) [250,000 species]: Unicellular protozoans and unicellular & multicellular (macroscopic) algae with 9 + 2 cilia and flagella (called undulipodia).\n\n3. Kingdom Fungi [100,000 species]: Haploid and dikaryotic (binucleate) cells, multicellular, generally heterotrophic, without cilia and eukaryotic (9 + 2) flagella (undulipodia).\n\n4. Kingdom Plantae [250,000 species]: Haplo-diploid life cycles, mostly autotrophic, retaining embryo within female sex organ on parent plant.\n\n5. Kingdom Animalia [1,000,000 species]: Multicellular animals, without cell walls and without photosynthetic pigments, forming diploid blastula.\n\n\nSo far those are the five Kingdoms I know of if there are a few more I have no idea but it is possible. Or you are confusing with bilogical organizations, which are 7

(A) protozoa\n(B) protozoa are eukaryotes (have membrane bound organelles), bacteria are prokaryotes (no nucleus, organelles, etc)\n(C) there are thousands of protozoans in Kingdom Protista (maybe even millions)\n(D) Protozoans are animal like because they are motile (some have flagella and/or cillia), SOME of them cannot produce their own food (via photosynthesis), so they have to get food from their environment, and some are sexually reproducing organisms.\n(E) via sexual reproduction\n\n(F) next time pay attention in class :)

Any organism which lives inside the cells or body of another organism.  The word basically means living together.\n\nSome endosymbiosis "living arrangements" are vital for survival (i.e. the host would die without the other organism).\n\nIt is sort of like a partnership....  the host organism provides a "safe place to live" and the guest provides food (sort of the cook if you like).\n\nNot all guest are welcome though... sometimes they can hurt or kill the host -- they are mostly uninvited guests.\n\nI hope that simplifies it a bit!  There is alot more info at the web link below.

Your question is to wide... protozoans are too big a group to tell their economic importance as a whole. You'll first have to find each and everyone of the organisms of the protozoan taxa than causes any disease (e.g. Plasmodium - malaria), then find out if there are estimates of their economic importance... then make the math.\nNext, you'll need to find out which protozoans may contribute to any industrial process. Who knows, there may be some species that is used to produce something... (as Sacharomyces cereviceae is used to produce beer)\nNext, find out the economic importance of protozoans as cell models in scientifical experiments...\nNext, find out the economic importance of protozoans as a fundamental part of the trophic chain in the oceans, and what would happen to the fish inductry around the world if they were gone...\nSo your question may no have as yet an estimate

I believe, that you are looking for amoeba.\nAmoeba's are from the kingdom: Zooplankton,  which has animal like characteristics. The Amoeba, in particular, belongs to the phylum: sarcodina which have characteristics such as having a coinceboid shape (no shape), and being able to flow by extending it's cell membrane to form false feet (pseudopod).\n\nBut, there are still several others that can be classified in this category: Paramecium cordatum (from the phylum: ciliophora), Trypanosoma gambiensis (from the phylum: mastigophora), and Plasmodium vivox (from the phylum: sporozoa)\nAs you see, there is more then one choice in this matter.\n\nHope this helps!

You are talking about PAMPs: Pathogen-associated molecular patterns. They are small molecules or parts of molecules typically associated with pathogenicity. They are never found in the host organism and can be used as a way for the immune system to identify a foreign agent. The lipopolysaccharides (LPS) mentioned in the previous answer are an example in prokaryotes. So are bacterial flagellins. Some mucin-like glycoproteins in protozoa like trypanasomes are thought to be eukaryotic PAMPs.

I think you're looking for a "symbiotic" relationship rather than a "parasitic" one. In a symbiotic relationship the two species rely on each other for survival or they help each other out in some way.\n\n"An example of mutual symbiosis is the relationship between clownfish of the genus Amphiprion (family, Pomacentridae) that dwell among the tentacles of tropical sea anemones. The territorial fish protects the anemone from anemone-eating fish, and in turn the stinging tentacles of the anemone protect the clownfish from its predators (a special mucus on the clownfish protects it from the stinging tentacles)."

Virus is not a protozoa\nviruses are very smaller living organisms than protozoans.\nThese two are coming in different categories.

Basically diplobiont. \nIn other organisms (plants, fungi), there are longer haploid or haploid + diploid phases. \nMetazoans are diploid; the only haploid stage in their life cycle are the gametes, which fuse to form the diploid zygote.

There are a number of examples in which prokaryotic organisms coalesce into multicellular structures. One of those examples are in a group of bacteria called myxobacteria. In this case, myxobacteria form what's called fruiting bodies as part of their life cycle (see the link below for a picture of a fruiting body).

the first multicellular being was Dictyostelium from symbiotic realtionship

Protozoa (in Greek protos = first and zoon = animal) are single-celled eukaryotes (organisms with nuclei) that show some characteristics usually associated with animals, most notably mobility and heterotrophy. They are often grouped in the kingdom Protista together with the plant-like algae. In some newer schemes, however, most algae are classified in the kingdoms Plantae and Chromista, and in such cases the remaining forms may be classified as a kingdom Protozoa. The name is misleading, since they are not animals.\n\nProtozoa have traditionally been divided on the basis of locomotion, although this is no longer believed to represent genuine relationships:\n\n    * Flagellates\n    * Amoeboids\n    * Sporozoans: Apicomplexa, Myxozoa, Microsporidia\n    * Ciliates\n\nMost protozoans are too small to be seen with the naked eye - most are around 0.01-0.05 mm, although forms up to 0.5 mm are still fairly common - but can easily be found under a microscope. Protozoa are ubiquitous throughout aqueous environments and the soil, and play an important role in their ecology. A few are also important parasites.

There are any number of examples. \n\nFor example many plant species and even entire communities have distributions controlled by soil type to the degree that it is normal to refer to sandstone communities or basalt communities.
