(1894 protists and Plants, 1895 Vertebrates, 1896 Invertebrates).
It seems desirable to do the same for the science of the protists, or unicellular organisms.
Human psychology is inseparably connected with comparative animal psychology, and this again with that of the plants and protists.
This monogenetic propagation is very common among the protists, both protophyta and protozoa.
The great majority of the protists have the appearance of real, nucleated cells.
It is only in the case of the protists that the morphological unity is bound up with the physiological.
protist pro·tist (prō'tĭst)
A unicellular, eukaroytic organism belonging to the former taxonomic kingdom Protista.
Any of a large variety of usually one-celled organisms belonging to the kingdom Protista (or Protoctista). Protists are eukaryotes and live in water or in watery tissues of organisms. Some protists resemble plants in that they produce their own food by photosynthesis, while others resemble animals in consuming organic matter for food. Protist cells are often structurally much more elaborate than the cells of multicellular plants and animals. Protists include the protozoans, most algae, diatoms, oomycetes, and the slime molds. Also called protoctist. See Table at taxonomy.
