  2. Protist - Wikipedia

    en.wikipedia.org/wiki/Protist

    A protist (/ ˈ p r oʊ t ɪ s t / PROH-tist) or protoctist is any eukaryotic organism that is not an animal, land plant, or fungus.Protists do not form a natural group, or clade, but are a polyphyletic grouping of several independent clades that evolved from the last eukaryotic common ancestor.

  3. Marine protists - Wikipedia

    The diagram on the right is an overview of the interactions between planktonic protists recorded in a manually curated Protist Interaction DAtabase (PIDA). The network is based on 2422 ecological interactions in the PIDA registered from ~500 publications spanning the last 150 years.

  4. Taxonomy of Protista - Wikipedia

    en.wikipedia.org/wiki/Taxonomy_of_Protista

    A protist (/ ˈ p r oʊ t ɪ s t /) is any eukaryotic organism (one with cells containing a nucleus) that is not an animal, plant, or fungus.The protists do not form a natural group, or clade, since they exclude certain eukaryotes with whom they share a common ancestor; [a] but, like algae or invertebrates, the grouping is used for convenience.

  5. Protistology - Wikipedia

    en.wikipedia.org/wiki/Protistology

    Protistology is a scientific discipline devoted to the study of protists, a highly diverse group of eukaryotic organisms. All eukaryotes apart from animals, plants and fungi are considered protists. [1]

  6. Protist locomotion - Wikipedia

    en.wikipedia.org/wiki/Protist_locomotion

    The 16-cell Gonium colony shown in the diagram on the right is organized into two concentric squares of respectively 4 and 12 cells, each biflagellated, held together by an extracellular matrix. [51] All flagella point out on the same side: It exhibits a much lower symmetry than Volvox, lacking anterior-posterior symmetry.

  7. Heliozoa - Wikipedia

    en.wikipedia.org/wiki/Heliozoa

    Instead, "heliozoa" is regarded as a descriptive term applying to various lines of protists. The primary groups include: [ 6 ] Actinophryida , Pedinellida and Ciliophryida (currently in Stramenopiles )

  8. Protozoan infection - Wikipedia

    en.wikipedia.org/wiki/Protozoan_infection

    Diagram of Plasmodium structure. Mixotrophic protists obtain nutrients through organic and inorganic carbon compounds simultaneously. [1] All cells have a plasma membrane. In a protist, the plasma membrane is also known as the plasmalemma. Just below the plasma membrane, and in the inner fluid region, cytoplasm can be found.

  9. Foraminifera - Wikipedia

    en.wikipedia.org/wiki/Foraminifera

    Foraminifera (/ f ə ˌ r æ m ə ˈ n ɪ f ə r ə / fə-RAM-ə-NIH-fə-rə; Latin for "hole bearers"; informally called "forams") are single-celled organisms, members of a phylum or class of Rhizarian protists characterized by streaming granular ectoplasm for catching food and other uses; and commonly an external shell (called a "test") of diverse forms and materials.
