Question

The wall of rhizopus hyphae is composed of
A.Cellulose
B.Chitin
C.Pectin
D.Hemicellulose

Answer 1

The rhizopus is one of the saprophytic group fungus which feed on the dead and decaying matter for their development.

Complete answer:
1: The hypha is the vegetative part of the fungus, it is one of most important part of the fungus body if hypha get damaged then the new fungus can’t be produce therefore the hypha is protected under a strong chemical layer to protect the hypha from the harsh environment conditions.
2:The hypha of the fungus is a multicellular filamentous structure which is closely covered by an outer layer , each compartment is separately covered by the protective layer.
3: In the tubular , filamentous structure each cell is divided with the help of a septa that is a horizontal line in the hypha.
4: The outer strong covering is made up of a chemical polymer that is made up of N acetylglucosamine that is commonly known as chitin.
5: chitin is one of the natural biopolymers that is present in nature as a strong outer covering.
6: It also made the exoskeleton of the different organisms in nature like the arthropods, nematodes.

So here option B is correct.

Note:
In insects it also supports the cuticles that are present in the outer epidermis layer of the insect and protects them from causality because of the outer environment. It is also present in the gut lining of the epithelial cells. The cell wall of the fungus is also made up of chitin material.
