Does Myxomycota have cell wall?

The Myxomycota or slime molds, are fungus-like organisms. They are characterised by the absence of cell wall from their amoeboid,’ animal-like vegetative or assimilatory phase.

What is somatic phase?

The somatic phase consists of coenocytic mass of highly granular protoplasm containing hundreds or thousands of nuclei and vacuoles without cell walls, but delimited only by a thin plasma membraneā€”a plasmodium (pl. plasmodia) (Fig. 321A).

What organisms are in the Myxomycota phylum?

Phylum: Myxomycota (Plasmodial Slime Molds) Other groups in this kingdom include cellular slime molds and protostelids. The three groups are monophyletic (Table 1). Of the three groups of slime molds, we will only cover the plasmodial slime molds.

Why are Oomycota not fungi?

The Oomycota were once classified as fungi, because of their filamentous growth, and because they feed on decaying matter like fungi. The cell wall of oomycetes, however, is not composed of chitin, as in the fungi, but is made up of a mix of cellulosic compounds and glycan.

Does slime mold have nuclei?

Plasmodial slime molds, like Physarum shown here, are basically enormous single cells with thousands of nuclei. They are formed when individual flagellated cells swarm together and fuse. The result is one large bag of cytoplasm with many diploid nuclei.

Are slime molds absorptive?

Fungus-like protists are molds. Molds are absorptive feeders, found on decaying organic matter. They resemble fungi and reproduce with spores as fungi do. Examples of fungus-like protists include slime molds and water molds.

What is the meaning of Myxomycota?
