A) protonema
B) Plasmodium
C) fruiting body
D) mycelium
Correct Answer: B
Solution :
The members of Myxomycetes are called slime moulds because they contain and secrete slime. They are included in lower fungi. Their somatic phase is a multinucleate, diploid holocarpic Plasmodium (a product of syngamy). In Plasmodium, propagation occurs through fission or thick walled cysts or sclerotium like structure. Reproduction takes place by the formation of uninucleate, thick walled resting spores which are produced within minute fruiting bodies like structures, ie, the sporangia, however, the true fruiting bodies are absent in slime moulds. Protonema is a haploid, branched filamentous structure, produced by the germination of moss spore, that produces new plants by budding. Fruiting body is a special fungal structure that bears sexually or asexually derived spores. Mycelium is the total mass of hyphae of a fungus that constitutes the vegetative body.
