Diversity Introduction - 5 Eukaryotic Organisms (Domain Eukarya) The Domain Eukarya includes three kingdoms of multicellular organisms that can readily be distinguished from each other, and the “everything else” (or the "dreaded" protists) being revisited by systematic biologists. Kingdom Plantae Photosynthetic Autotrophs Obtain inorganic materials from the external environment and process them into the organic compounds needed for life. Cells secrete a cell wall exterior to the plasma membrane Classified by life history variations, as well as presence or absence, and types of vascular tissue Some traditional "algae" groups, placed within the protists group in the mid-1900's are now being allied with plants. They include the red and green algae. Algae, which are aquatic organisms, have little or no tissue development, but share, in particular, similarities in chloroplast development with the land plants.
