Question

Thalloid body of a slime mold is a
A.Protonema
B.Mycelium
C.Plasmodium
D.Fruiting body

Answer 1

Hint:The unrelated eukaryotic organisms that live freely as single cells but can aggregate together to form multicellular reproductive structures are called the slime molds. Earlier these are classified under the class of fungi but no longer present in the later due to their unimproved characters.

Complete answer:During the shortage of the food supply, many of the single-celled organisms will combine and start moving towards their required placement in search of food or shelter as a single body. These can detect food sources and are more prone to airborne chemicals in this stage. Changing the shape of the body was done readily with its functions and also forms the stalks that involve the production of fruiting bodies, releasing countless spores and carrying enough light towards the wind. The main source of food for these amoebae are feeding bacteria and these are haploid.
These amoebae form zygotes by encountering the correct mating types and thus leads to the formation of the plasmodia. The nucleus is present without cell membranes that grow in mm of size. Fuligo septica is the species of a rare type that includes an in-network of rotting logs. Protoplasmic strands are developed from the Plasmodium, an interconnected network.
Hence, the correct option is (C) Plasmodium

Note: The streaming protoplasm within a plasmodial strand can reach speeds of up to 1.35 mm per second, which is the fastest rate recorded for any microorganism. The migration of the Plasmodium is accomplished when more protoplasm streams to advancing areas and protoplasm are withdrawn from rear areas. When it is vain in food supply the migration of Plasmodium towards the surface of its substrate occurs that transforms into the fruiting bodies that are rigid.
