The upcoming discussion will update you about the differences between plasmodiophora and physarum.
Difference # Plasmodiophora (Plasmodiopohromytes):
1. Plasmodiophora is an internal obligate parasite (endoparasite).
2. It is parasitic in its mode of nutrition.
3. The life cycle comprises two distinct phases, the haplophase and the diplophase.
4. The haplophase starts with the germination of resting spore or cyst in the soil comprises in addition the zoospores, myxamoebae, haploid, primary plasmodium (gametothallus), and the isogametes.
5. The zygotes are founds in the cortical cells of the roots where each develops into a diploid secondary plasmodium (sporothallus). At maturity it fills the lumen of the hoist cortical cell.
6. The diploid protoplast of the secondary plasmodium reaching maturity, forms no fructification.
7. The diploid secondary plasmodium itself, at maturity undergoes meiosis to from haploid resting spores or cysts.
8. Meiosis takes place at the precleavege stage.
9. The mature resting spores are released in the soil by decomposition and decay of the root clubs of the host by soft rot bacteria.
10. The thick spore wall is chitinous in nature.
11. Nuclear division is peculiar. The vegetative nuclear division is of cruciform type and nuclear division is of cruciform type and meiosis has an akaryote stage.
Difference # Physarum (Mysomycetes):
1. It is a free living amoeboid myxomycete.
2. It is phagotrophic in its mode of nutrition.
3. The resting spore or cyte germination in the soil to give rise to swarm cells and myxamoebae which function as gametes.
4. The resting spore or cyst germinates in the soil to give rise to swarm cells as gametes. The haplophase is thus replaced by a few haploid cells only namely swarm cells or myxamoebae.
6. Reaching maturity, the diploid plasmodium became converted into or more sessile or staked fruit bodies called the sporangia or sporophores.
7. The diploid protoplast of the sporangium under goes meiosis to from haploid resting spores or cysts.
8. Meiosis takes place at the post –cleavage stage.
9. The peridium disintegrates exposing the spore mass supported by the capillitium. Wind, mites and rain play an important role in dispersing the spores from the exposed spore mass.
10. The spore wall contains cellulose.
11. Both of them are absent in the slime molds.
