Is Protozoa the bacteria kingdom?
459953
Protozoans are single-celled organisms such as amoeba, euglena, vorticella and others, characterized by possession of a true nucleus in the cell.\n\nBacteria do not have a nucleus.  They are usually placed in the Kingdom Monera. \n\nSpecialists in single-celled organisms have found that the standard system of five kingdoms doesn't fit well with the vast diversity seen in single-celled organisms.  They use as many as 30 or 40 Kingdoms to classify all these critters.  Most of us don't care enough about single-celled critters to bother to learn the bajillions of different varieties.

There are five kingdoms. \n\nIt is disputed which kingdom viruses belong in because it is disputed whether viruses are living things since they do not reproduce (without a host cell) and they do not metabolize food or catalyze energy (without a host cell)\n\nHowever, bacteria is part of the kingdom monera so likely viruses would be in that same kingdom

Bacteria are prokaryotic organisms. They are mostly unicellular, and they have no nucleus and other cell structures.\n\nProtists and Fungi, on the other hand, are eukaryotes, which are unicellular or multicellular organisms that have a nucleus and complex structures like mitochondria and chloroplasts.\n\nfor more details, go to an encyclopedia website like http://www.wikipedia.org

Moneran - Includes bacteria, blue green algae, and primative pathogens.  Considered the most primative kingdom, it represents prokaryotic life forms - they have no distinct nuclei\n\nProtista - simples eukaryotes.  Include protozoa, unicellular and multicellular algae, and slime mold.  Ancestor organisms to plants, animals, fungi; most can move around by means to flagella\n\nFungi - includes mushroom, bread molds, and yeasts.  Fungi lack the ability to photosynthesize, so they are called decomposers, breaking down and feeding on dead protoplasm.\n\nPlantae - have the ability to photosynthesize, so they are called producers.  They are two major phyla, Bryophyta, or mosses and Tracheophyta - which have vascular systems and include most of the plants you know.\n\nAnimalia - produce energy by consumering other organisms, so they are called consumers.  Can be either vertebrates, phylum Chordata, or invertebrates such as mollusks, arthopods, sponges, coelenterates, worms, etc.

These are single-celled (unicellular) organisms, and\nhave a well-defined membrane-bound nucleus.\nTheir modes of nutrition may be quite varied.\n• Active feeders: Some protists like Amoeba and\nParamecium (Fig. 23.5) ingest food like most\nanimals. Very often these are also referred to as\nProtozoa (protos: primitive, zoon: animal).\n• Photosynthesizers: Some protists like Euglena\n(Fig. 23.3) have chlorophyll and manufacture\ntheir own food like the plants.\n• Reproduction: Mostly asexual reproduction by\nfission and some reproduce sexually.\n• Occurrence: Many protists live freely in water\nor in soil and many are harmful parasites which\ncause diseases. Some of the protists are\npathogenic, such as Entamoeba histolytica that\ncauses dysentery and Plasmodium vivax that\ncauses malaria.

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.

Unicellular organisms are placed in both Monera and Protista.  Also there are Archaeans that are single celled prokaryotes that are not placed in either Monera or Protista and are given their own domain called Domain Archaea.  \n\nFor the old classification system unicellular organisms are broadly placed into Monera if they lack a nucleus.  Unicellular organisms are lumped into protista if they have a nucleus and membrane bound organelles, such as mitochodria, and in some cases chloroplasts.  \n\nFor example a bacterium does not possess a nucleus.  Therefore all bacteria are placed into Monera.  \nProtista contains many different kinds of unicellular organisms such as amoeba and green algae.  All of the protists will have a nucleus and mitochondria at the very least.

u must be knowing that all organisms are classified into five kingdoms-monera,protista,anemalia,fungi and alge.\n\nthe MONERA phlum[group] consists of bacteria which are prokaryotic in nature -i.e, the cell doesnot have membrane bound organneles or nucleus.\n\nthe Protista group consists of organisms that are eukaryotic in nature-that is they have well defined organneles.\nthis is one reason that bacteria is kept in two separate groups.

Maybe prokaryotes. But I'm not sure... I think there's still a debate about them cause they're not really living creatures... They are "alive" when they are inside a host, but otherwise, they're just lifeless proteins.. :)

*Digging out my encyclopedia* The first bacteria were observed by Antony van Leeuwenhoek in 1683 using a single-lens microscope of his own design. The name bacterium was introduced much later, by Ehrenberg in 1828, derived from the Greek word βακτηριον meaning "small stick". Louis Pasteur (1822-1895) and Robert Koch (1843-1910) described the role of bacteria as conveyors and causes of disease or pathogens.\n\nOriginally the bacteria were considered microscopic fungi (called Schizomycetes), except for the photosynthetic cyanobacteria, which were considered a group of algae (called Cyanophyta or blue-green algae). It was only with the study of detailed cell structure that it was realized they formed a fundamental group, separate from the other organisms. In 1956 Copeland gave them their own kingdom Mychota, later renamed Monera, Prokaryota, or Bacteria. During the 1960s the concept was refined and bacteria (now including cyanobacteria) were recognized as one of two major divisions of the living world, together with the eukaryotes. Eukaryotes were generally believed to have evolved from bacteria, later from assemblies of bacteria.\nhttp://www.aaaah.org/wiki/en/ba/Bacterium.htm\nBacteria (singular: bacterium) are a major group of living organisms. Most are microscopic and unicellular, with a relatively simple cell structure lacking a cell nucleus, and organelles such as mitochondria and chloroplasts. Their cell structure is further described in the article about prokaryotes, because bacteria are prokaryotes, in contrast to organisms with more complex cells, called eukaryotes.\nhttp://en.wikipedia.org/wiki/Bacteria

In the nucleus for eukaryote, and just floating around in a prokaryote.  The prokaryotes are Monera (bacteria) and Archaea.  More complex creatures are eukaryotes.\n\nSo nucleus is probably the answer you're looking for.

Archaea, Eukaryota and Bacteria are the fundamental classifications in what is called the three-domain system. Like bacteria, Archaea are single-celled organisms lacking nuclei and are therefore prokaryotes, classified as Monera in the alternative six-kingdom taxonomy. They were originally described in extreme environments, but have since been found in all types of habitats.\n\nThe archaeal lipids are unique because the stereochemistry of the glycerol is the reverse of that found in bacteria and eukaryotes. This is strong evidence for a different biosynthetic pathway. \nMost bacteria and eukaryotes have membranes composed mainly of glycerol-ester lipids, whereas archaea have membranes composed of glycerol-ether lipids. Even when bacteria have ether-linked lipids, the stereochemistry of the glycerol is the bacterial form. These differences may be an adaptation on the part of Archaea to hyperthermophily. However, it is worth noting that even mesophilic archaea have ether-linked lipids. \nArchaeal lipids are based upon the isoprenoid sidechain. This is a five-carbon unit that is also common in rubber and as a component of some vitamins common in bacteria and eukaryotes. However, only the archaea incorporate these compounds into their cellular lipids, frequently as C-20 (four monomers) or C-40 (eight monomers) side-chains. In some archaea, the C-40 isoprenoid side-chain is actually long enough to span the membrane, forming a monolayer for a cell membrane with glycerol phosphate moieties on both ends.
