Question

The multinucleate slimy mass of protoplasm which forms the body of slime moulds is called as
A. Plasmodium
B. Myxamoebae
C. Sporocytes
D. Per Plasmodium

Answer 1

Hint: The name of the nucleated slimy mass of protoplasm is similar to a parasite that is responsible for causing malaria. It is a fungi.

Complete answer:
Plasmodium, which belongs to kingdom Fungi, is a mobile multinucleate mass of cytoplasm.
It has no cell wall.
A vegetative phase of true slime molds or Myxomycetes is a well-defined characteristic of Plasmodium.
The genera include Plasmodiophora and Spongospora.
Protoplasm or Plasmodium consist of numerous diploid nuclei.
The plasmodium of a slime mold is formed from the fusion of gamete cells called myxamoebae or of swarm cells.
Myxamoebae are spores that are released from a slime mold.
It possesses pseudopodia or lobes of cellular material and are known for their amoeba-like appearance and behavior.
As a myxamoebae moves across a moist surface, it engulfs bacteria and fuses with a second myxamoebae, thereby initiating the development of a multinucleate plasmodium.
Plasmodia are shapeless and mobile fungi.
It slides over moist substrates, such as rotting logs and decaying leaves, and ingest bacteria and other organic matter.
When growth conditions of plasmodium are unfavorable, it becomes immobile, and the slime mold progresses to the next stage of its life cycle, marked by the growth of a fruiting body containing a sporangium, or spore case.

So, the correct answer is option A. Plasmodium.

Note: There is a difference between slime mould Plasmodium and the Plasmodium parasite. The former is the vegetative multinucleated slime mould and the later is a parasite of malaria, where the host for the disease is Human and carrier is female Anopheles mosquito.
