  Nearctica - Natural History - Protista
Although they have a formal name, the protists (Protista) is essentially a miscellaneous collection of all of the eucaryotic organisms that remain after the plants, animals, and fungi are removed.
You may wish to start with the general introduction to the classification of the protists listed below.

  Protista - MSN Encarta
Protista, group of comparatively simple organisms, called protists, that have characteristics of both plants and animals.
The term Protista was first used in 1862 by the German biologist Ernst Haeckel to describe microscopic organisms that were neither clearly animallike nor plantlike.
The classification of the Protista is currently based largely on the structure and organization of the cell, the presence of organelles, and the pattern of reproduction or life cycles.

 The Origins of Eukaryotic Diversity
Kingdom protista in the five-kingdom system is a paraphyletic kingdom, meaning that there exist a number of taxa (kingdoms) that are not included among the protists but nevertheless descended from protists (5ks)
The trend during the 1970s and 1980s was to expand the boundaries of Kingdom Protista to include some groups of multicellular organisms, such as seaweeds, classified in earlier versions of the five-kingdom system as either plants (in the case of seaweeds) or fungi.
In its expanded form, Kingdom Protista also encompassed phyla of funguslike organisms, such as the forms known as slime molds and water molds, which may have their closest relatives among the unicellular eukaryotes called amoebas.

The "Protista" is the first group of eukaryotic organisms that you will examine.
Protista is the oldest, most diverse, and most difficult to characterize of the eukaryote groups.
In general, members of the Protista are single-celled eukaryotic organisms that lack the distinctive features of other eukaryotes such as plants, animals, and fungi.

 Protist - Wikipedia, the free encyclopedia
The protists are a paraphyletic grade, rather than a natural (monophyletic) group, and do not have much in common besides a relatively simple organization (unicellular, or multicellular without highly specialized tissues).
At one time, bacteria were also considered protists, under the three-kingdom system of Animalia (corresponding closely to the modern kingdom), Plantae (which included Fungi as well as plants), and Protista (everything else).
Protozoa are mostly single-celled, motile protists that feed by phagocytosis, though there are numerous exceptions.

 Wikinfo | Protista
The Kingdom Protista or Protoctista is one of the commonly recognized biological kingdoms, including all the eukaryotes except for the plants, fungi, animals, and sometimes other groups which are treated in separate kingdoms.
Eventually the kingdom Protista was created to house these forms, with the classes of protozoa (corresponding roughly to the above) being promoted to phyla.

PROTISTA [Protista] or Protoctista, in the five-kingdom system of classification, a kingdom comprising a variety of unicellular and some simple multinuclear and multicellular eukaryotic organisms.
Protists, which are eukaryotes, have cells that have a membrane-bound nucleus, DNA that is associated with histone proteins, and organelles (e.g., mitochondria and chloroplasts).

The outbreak of this protist was quickly halted, but it's effects will be remembered by many Milwaukeans for a long time to come.
Thus, it shouldn't surprise you to find that some protists are microscopic while others are enormous in size...or that some protists are photosynthetic while others are not...or that some protists behave and move about their environment while others are completely immobile.

The diagnostic characters of the algal group as a whole were ill-defined, but nevertheless vastly different from the well-defined traits of the other two plant subkingdoms, namely the bryophytes and vascular land plants.

The general classification of groups within the algae is based partly upon the nature of the chlorophylls and accessory pigments present in the photosynthetic membranes.
