Question

Naked cytoplasm, multinucleated, and saprophytic are the characteristics of
A. Monerans
B. Protists
C. Fungi
D. Slime Moulds

Answer 1

Among the given options only one of them is known to have naked cytoplasm. Also multinucleated is a character of organisms which do not have the capability to divide their cell wall and reproduce by asexual reproduction only.

Complete answer:
By just seeing the options we can clearly rule out the option of fungi as they are not multinucleated and can reproduce via both sexual and asexual mode of reproduction. Here we are looking for organisms that can reproduce only via asexual means.
If we talk about monerans, then they are prokaryotes and consist of most of the unicellular organisms. Though they have asexual mode of reproduction but their cytoplasm is not naked and rather it is enclosed. So, we can rule out this option also. The other option provided to us is of protists, they have a similarity with the conditions provided to us. They are sometimes seen multinucleated and also saprophytic but if we talk about the nature of cytoplasm then there is a di8fference as the protists have a characterized layer developed around the cytoplasm.
The protists mainly consist of the eukaryotes and they can be unicellular or also multicellular organisms. Now we are left with the option of slime moulds, and if we look and analyze the characters of the slime moulds then we will see that they lack the capability to divide their cell wall, and they reproduce via budding methods. Moreover, the cytoplasm of the slime moulds is also naked.

Therefore, the correct answer is the Option D.

Note:
The reproduction in slime moulds happens when the conditions around the organisms are favorable and moist. They generally feed on the dead and decaying organisms and reproduce under moist conditions by forming a bud with the nucleus and some cytoplasm followed by the detaching of the buds under suitable conditions.
