Scientists dubbed the lifeform with the taxonomy Physarum polycephalum, but concede it does not hold to typical classification. P. polycephalum, also known as slime mold, is a single celled Eukaryotic organism that grows in the understory or damp, dark places (i.e. Sort all by: WARD470176-642 WARD470176-644. 3. The opening part covers two chapters on morphology, taxonomy, phylogeny, biosystematics, and evolutionary implications of Physarum and Didymium species. Small plasmodia can be fragmented into microplasmodia. This stage of the life cycle, along with its preference for damp shady habitats, likely contributed to the original mischaracterization of the organism as a fungus.

Scale bar ~0.5 cm. When exploring a petri dish, it would not double back to where it has already been before. In moving, the plasmodium may move along many fronts that are connected by veins. Acellular slime molds ( Myxomycetes ) are distinguished from cellular slime molds ( Acrasiales ) because the plasmodium (which is diploid) is a syncytium produced by multiple nuclear divisions (karyokinesis) without cytokinesis. The opening part covers two chapters on morphology, taxonomy, phylogeny, biosystematics, and evolutionary implications of Physarum and Didymium species. These include periodic events of the mitotic cycle in Physarum polycephalum.

The plasmodium is the active feeding stage of the organism and consists of a mass of multinucleate protoplasm. Class: Myxomycetes In this dormancy the slime mold becomes a hardened multinucleated mass which is called sclerotium. Ratings: 0.0 out of 5. 1983. Subclass: Endosporeae  Ridgway B. E, Durham C. H. A. J Cell Biol. Physarum bivalve. It ingests solid food particles in the same manner as an amoeba and can also absorb dissolved nutrients. 1976 April 1; 69(1): 223–226. Classification. Scientists dubbed the lifeform with the taxonomy Physarum polycephalum, but concede it does not hold to typical classification. It acts like an animal but appears to be more of a fungus.

Taxonomy. Directions are given for: acquiring the organism; activating it; observing its life cycle; and viewing protoplasmic streaming. Also, while widely considered to be a lower eukaryote, study of aminoacyl-tRNAs has shown that P. polycephalum has patterns of codon recognition that are more like higher plants and animals, and lower fungi.
