Examples

  • Metazoans (multicellular organisms) are commonly distinguished from colonies of protista, somewhat arbitrarily, on the basis of their having more than one functional type of non-reproducing cell; but the question of by what criteria multicellular bodies can properly be considered individual organisms, as more than a matter of convenience or convention, has not been decisively raised.

    Individuals, societies, and the classification of organisms

  • Among certain infusoria and other protista, they do, in fact, remain together and build up branching colonies.

    Scientific American Supplement, No. 810, July 11, 1891

  • Cambrian formation in North America, is really an organism and not an inorganic form, the earliest vestiges of animal life we can find are the rhizopodes or foraminifera; and these organisms belong to the lowest stage of life -- to that stage which forms a kind of undeveloped intermediate member between the vegetable and animal kingdom, Häckel's kingdom of the protista.

    The Theories of Darwin and Their Relation to Philosophy, Religion, and Morality

  • Häckel's labors rendered still greater service to the Darwinian theory by dividing the organic world into three kingdoms: the protista kingdom, the vegetable kingdom, and the animal kingdom, -- a division which solves in a most simple way the difficulty that was felt more and more of securing for the lowest organisms a place among the animals or plants.

  • He further aided the theory by leaving the choice open to adopt either a uniform or multiform pedigree of the organisms and their kingdoms and classes, and by treating each class under both points of view; and finally, by fascinating experiments to bring before us in detail the hypothetical pedigrees of all classes of organisms from the protista kingdom up to man.

  • From protozoa or protista to plants and animals the graduation is closer than from magnetised iron to vitalised sarcode.
