  2. mycelium

  3. rhizoid

  4. fruiting body

Show answer
Correct Option: B
Explanation:

A.Hypha – a filament of mycelium is called hypha.

B.mycelium – a network of filamentous structure appear in the body of fungus is called mycelium.

C.Rhizoid -  root like hyphae appear in some fungi are called rhizoids.

D.Fruiting body – specialised structure formed after fertilizaiton in ascomyetis and basidiomycetis fungi is called fruiting body. It is made up of secondary mycelium.

So, the correct option is ‘mycelium’.

The fungi are

  1. Autotrophic

  2. Holotrophic

  3. Chemotrophic

  4. Heterotrophic

Show answer
Correct Option: D
Explanation:

Fungi are multicellular, eukaryotic, heterotrophs, that acquire their nutrients by absorption. Heterotrophic nutrition is a type of nutrition which is obtained by digested organic compounds. They feed on dead or decaying organic matter.

Therefore, the correct answer is option D.
