types of protist, are a diverse group of eukaryotic microorganisms, types of protist were treated as the kingdom protista but this group is no longer recognized in modern taxonomy. Instead, it is better regarded as a loose grouping of 30 or 40 disparate phyla with diverse combinations of trophic modes, mechanisms of motility, cell coverings and life cycles.
types of protist do not have much in common besides a relatively simple organization either they are unicellular, or they are multicellular without specialized tissues. The term protista was first used by Ernst Haeckel in 1866.
Protists were traditionally subdivided into several groups based on similarities to the higher kingdoms, the one types of protist celled animal like protozoa, the plant like protophyta mostly one celled algae, and the fungus like types of protist slime molds and water molds, types of protist have been replaced by phylogenetic based classifications, types of protist are still useful as informal names for describing the morphology and ecology of protists.
Protists live in almost any environment that contains liquid water. Many protists, such as the algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean as part of the plankton. Other protists, such as the kinetoplastids and apicomplexa are responsible for a range of serious human diseases, such as malaria and sleeping sickness.
The first division of the protists from other organisms came in the 1820s, when the german biologist introduced the word protozoa to refer to organisms such as ciliates and corals. This group was expanded in 1845 to include all unicellular animals, such as foraminifera and amoebae. The formal taxonomic category protoctista was first proposed in the early 1860s, the protists should include primitive unicellular forms of both plants and animals, in addition to the then traditional kingdoms of plants, animals and minerals.
type theory is any of several formal systems that can serve as alternatives to naive set theory, or the study of such types of protist, types of protist is language theory, types of protist type theory can refer to analysis and study of type systems, although some scientists limit the terms meaning to the study of abstract formalisms.
types of protist invented the first type theory in response to discovery version of set theory was afflicted with paradox, types of protist type theory features prominently in paradox by first creating a of types, then assigning each mathematical entity to a type. Objects of a given type are built exclusively from objects of preceding types.
