What is an example of Plasmodial fungi?
plasmodium, in fungi (kingdom Fungi), a mobile multinucleate mass of cytoplasm without a firm cell wall. A plasmodium is characteristic of the vegetative phase of true slime molds (Myxomycetes) and such allied genera as Plasmodiophora and Spongospora.
What causes the Myxamoebae to aggregate?
The bacteria secrete folic acid, which attracts the myxamoebae. When the supply of bacteria is depleted, the myxamoebae enter the aggregation stage. During aggregation, starvation initiates the production of protein compounds such as glycoproteins and adenylyl cyclase.
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 plasmodium in slime Moulds Class 11?
Slime moulds are saprophytic protists. Under suitable conditions, they form an aggregation called plasmodium, and during unfavourable conditions, the plasmodium differentiates and forms fruiting bodies bearing spores at their tips.
What type of environment do slime molds like?
They feed on microorganisms that live in any type of dead plant material. They contribute to the decomposition of dead vegetation, and feed on bacteria, yeasts, and fungi. For this reason, slime molds are usually found in soil, lawns, and on the forest floor, commonly on deciduous logs.
Is plasmodium an Amoebozoa?
Structure. A plasmodium is an amoeboid, multinucleate, and naked mass of cytoplasm that contains many diploid nuclei. The resulting structure, a coenocyte, is created by many nuclear divisions without the process of cytokinesis, which in other organisms pulls newly-divided cells apart.
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.
What is the difference between the plasmodium form of a Plasmodial slime mold and the Pseudoplasmodium form of a cellular slime mold?
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 does Myxamoebae meaning?
Myxamoebae are spores released from a slime mold that possess pseudopodia (lobes of cellular material) and are known for their amoeba-like appearance and behaviour.
Is Dictyostelium unicellular or multicellular?
Dictyostelium are social amebas, meaning that they live as both unicellular and multicellular organisms. Dictyostelium start out as separate, individual cells.
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.
How are slime molds made?
1. 12: Plasmodial slime molds exist as large amoebae filled with many diploid (2n) nuclei. When conditions signal the amoeba to end its vegetative phase (lack of food or moisture), the plasmodium coalesces into a fruiting structure (sporocarp). Inside the sporocarp, the nuclei undergo meiosis to produce haploid spores.
