What is a pseudoplasmodium composed of?

A pseudoplasmodium is a multicellular uninucleate structure of the Cellular slime molds composed of aggregated haploid amoebae. It is not a feeding stage.

How is plasmodium formed?

The plasmodium of a slime mold is formed from the fusion of myxamoebae or of swarm cells (gametes). ... As a myxamoeba moves across a moist surface, it engulfs bacteria and eventually fuses with a second myxamoeba, thereby initiating the development of a multinucleate plasmodium.

What is the difference between the plasmodium and sclerotium of a slime mold?

The plasmodium also has the ability to subdivide and establish separate plasmodia. Conversely, separate plasmodia that are genetically similar and compatible can fuse together to create a larger plasmodium. If conditions become dry, then the plasmodium will form a sclerotium, essentially a dry and dormant state.

How do Plasmodial slime molds reproduce?

Under favorable conditions, plasmodial slime molds reproduce by forming a reproductive stalk containing spores. This reproductive stalk looks spherical or even popsicle-like on top. When the time is right, these stalks will release the spores and new slime molds will proliferate.

What is the difference between phylum Myxomycota and phylum Acrasiomycota?

Slime molds are organisms in two taxonomic groups, the cellular slime molds (Phylum Acrasiomycota) and the plasmodial slime molds (Phylum Myxomycota). Organisms in both groups are eukaryotic (meaning that their cells have nuclei) and are fungus-like in appearance during part of their life cycle.

What is the difference between Plasmodium and Pseudoplasmodium?

A plasmodium is a multinuclear, acellular (single large cell is acceptable answer) feeding stage of the Myxomycota. The nuclei in the plasmodium are diploid. A pseudoplasmodium is a multicellular uninucleate structure of the Cellular slime molds composed of aggregated haploid amoebae. It is not a feeding stage.

What is the difference between Plasmodial and cellular slime molds?

Plasmodial slime molds form a single-celled, multinucleate mass, whereas cellular slime molds form an aggregated mass of separate amoebas that are able to migrate as a unified whole. Slimes molds feed primarily on bacteria and fungi and contribute to the decomposition of dead plants.

Are slime molds protists?

Slime molds are protists, which are eukaryotic microorganisms that can't be classified as belonging to either the animal, plant, fungus, or bacteria kingdoms. Slime molds are a type of protist that aggregate into colonies and ingest bacteria, fungal spores, and other protists.

Are slime molds Saprophytic protists?

Slime molds are saprophytic organisms that form vegetative amoeboid plasmodia and spores.

What eats slime mold?

Two of the main groups are the cellular slime molds (Dictyosteliida) and the plasmodial or acellular slime molds (Myxogastria). ... They are eaten by many small animals (there are little, shiny, brown beetles apparently feeding – and cavorting – in the pink slime mold), and some are said to be edible by humans.

What are slime molds made out of?

Phylogenetically, slime molds are more related to the amoeboid protozoa than the fungi. There are two types of slime molds. The cellular slime molds are composed of single amoeboid cells during their vegetative stage, whereas the vegetative acellular slime molds are made up of plasmodia, amorphic masses of protoplasm.

Is slime mold unicellular or multicellular?

The so-called cellular slime mold, a unicellular organism that may transition into a multicellular organism under stress, has just been found to have a tissue structure that was previously thought to exist only in more sophisticated animals.

Is slime mold autotrophic or heterotrophic?

Like plants, slime molds have cellulose in the cell walls of their spores. Unlike plants, slime molds are heterotrophs! Though they were formally classified as fungi, slime molds do not have chitin in their cell walls and have a diplontic life cycle (Figure 5.2.
