But there is also nosharp line of demarcation between the Prntixta on the one side andanimals and plants on the other. Some Protista are, chiefly by theirmethod of nutrition, more nearly related to plants, others to latter are called Protozoa, in contradistinction to all other animals,which are classed as Metazoa. THE FIEST RACE OR PHYLUM OF THE ANIMAL KINGDOM. PROTOZOA. Systematic Review. CLASS I. Monera. Simplest organisms. Small masses of protoplasm of varied changing form, inwhich till now no nuclei have been demonstrated. Locomotion and ingestion offood by means of blunt (amoeboid) or long and tine processes (pseudopodia). Repro-duction by fission and gemmation. All Monera live in water. Prot/nnnh
