Nearly all single-celled eukaryotes that are either heterotrophic or photosynthetic belong to the kingdom?
596485
Just going with what Jag said, there doesn't seem to be any correct answer.\n\nAnimalia are never photosynthetic.\n\nEubacteria are never eukaryotes.\n\nFungi are never photosynthetic.\n\nPlantae are never single celled.\n\nNone of the answer is correct. In point of fact most single-celled eukaryotes that are either heterotrophic or photosynthetic belong to the kingdom Protista. But Protista isn't one of the options given.\n\nI think your teacher stuffed up the question.

Just to add to Acraz's answer, Plants and fungi are also made up of eukaryotic cells. \nOnly bacteria are prokaryotic.

Most members of that kingdom are unicellular, but some are colonial and there are some that a simple multicellular.\n\nVolvox is a green alga and makes its own food, so it is an autotroph.  Radiolaria are heterotrophs.

< The golden algae or chrysophytes are a large group of heterokont algae, found mostly in freshwater. Originally they were taken to include all such forms except the diatoms and multicellular brown algae, but since then they have been divided into several different groups based on pigmentation and cell structure. They are now usually restricted to a core group of closely related forms, distinguished primarily by the structure of the flagella in motile cells, also treated as an order Chromulinales. It is possible membership will be revised further as more species are studied in detail. They come in a variety of morphological types, originally treated as separate orders or families.

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.

The domain would be Eukarya--Eukaryotic cells. Some folks would put protista in Kingdom Protista within the larger superkingdom or domain Eukarya. \n\nHowever, the word "protist" conveys the meaning of "eukaryote that isn't a plant, animal, or fungus." It includes "simpler" forms:   no complex development from embryos, no extensive cell differentiation, etc.\nBut, recent studies of protist DNA and ultrastructure show that they are not monophyletic.  The protists are quite diverse and  probably should be classified in several kingdom-level taxa. \nIn other words, the "Kingdom Protista" really represents more than one group.  It contains organisms which are more closely related to members of other kingdoms than they are to other protists.

Any living organism that obtains its energy from organic substances produced by other organisms can be defined as heterotroph. All animals and fungi are heterotrophs,mushroom are fungi that feed on organic substances thus it is heterotroph.

Hey, this is a question I asked my professor, how funny, lol. \n\nFirst of all, it's important to note the differences between a prokaryotic and a eukaryotic cell.  \n\nCells that lack a membrane-bound nucleus are called prokaryotes (from the Greek meaning before nuclei). These cells have few internal structures that are distinguishable under a microscope. Cells in the monera kingdom such as bacteria and cyanobacteria (also known as blue-green algae) are prokaryotes. Prokaryotic cells differ significantly from eukaryotic cells. They don't have a membrane-bound nucleus and instead of having chromosomal DNA, their genetic information is in a circular loop called a plasmid. \n\nTake a look at this picture:  http://library.thinkquest.org/C004535/media/prokaryote.gif\n\nEukaryotic cells comprise all of the life kingdoms except monera. They can be easily distinguished through a membrane-bound nucleus.  Eukaryotic cells also contain many internal membrane-bound structures called organelles. These organelles such as the mitochondrion or chloroplast serve to perform metabolic functions and energy conversion. \n\nTake a look at this picture:  http://library.thinkquest.org/C004535/media/eukaryote_animal.gif\n\nFor a brief and quick response, ...a eukaryotic cell is a larger cell with distinctly more organelles within the cell.  They differ in size greatly :)

In my biology class we were taught they are divided into 3 groups based on nutrition.  Protozoa, algae, and fungus like protists.  Protozoa are animal like in that they are heterotrophs.  Algae are autotrophs.  Protozoa are further classified by mobility (cilia, flagella, or sporozoa)

The count is difficult, since you don't say what do you mean by plants. Not joking.\nIn botany fungi aren't plants, nor mosses, neither algae.\nThe term plant is scientifically restricted to eucariontic life forms that process their own food from sun light, CO2 and water, live on land (mainly), but WITH  a VASCULAR SYSTEM well developed.\nso, please narrow your question, or expand it, anyway a pleasure to discuss this topics, TKS!

An ameba. It is a single cell organism according to science book years ago. But I suspect the earlier answer as a virus is also correct.

not the smallest... but unicellular, euchariothic, living form. Reproduces by bipartition.

Then there are different species such as campanula, citrina, comunis etc.
