Question

Which group of bacteria is known as ‘ray fungi’?
A. Mycobacteria
B. Mycoplasma
C. Actinomycetes
D. Myxobacteria

Answer 1

Hint: Bacteria are the prokaryotic microorganisms which have a single cell and lack nuclei and other organized cell structures. There are various species of bacteria like pathogenic, non infectious, some have played a role in decay, fermentation, nutrient recycling and nitrogen fixation. They are present in various shapes and sizes.

Complete Answer:
- Bacteria basically divided into two types’ gram-positive bacteria and gram-negative bacteria.
- This classification is based on the microbiological staining procedure.
- Ray fungi are also known as Actinomycetes and are the prokaryotic microorganisms (bacteria).
- Actinomycetes are filamentous and are not movable.
- They made mycelium which consists of narrow hyphae and show the properties of both fungi and bacteria.
- Ray fungi form the normal part of the mouth flora in humans.

So, the correct answer is ray fungi known as Actinomycetes bacteria.

Additional information:
- Genus of Actinomycetes is an actinobacteria class of bacteria and all are Gram-positive.
- These grow in the anaerobic (Without oxygen) conditions.
- Endosperm formation does not take place in the actinomycetes and these are rod-shaped.
- They have some medicinal value because they make antibiotics like streptomycin, actinomycin and chloromycin.

Note: Actinomycetes known for the important role in soil ecology and produce a number of enzymes which help degrade organic plant material, lignin, and chitin. That is why the presence of actinomycetes is important in the formation of compost.
