Answer:
Hyphae absorb nutrients from the environment and transport them to other parts of the thallus.
Explanation:
The large volumes of hyphae within the mycelium perform a fundamental role by obtaining nutrients from the organic substrates from the surrounding of the fungus. Hyphae play different kinds of functions in fungi. 
They contain cytoplasm or cell sap. They also contain the nuclei, which include genetic material. Hyphae absorb nutrients from the environment and transport them to other parts of the thallus. 
The thallus is the fungus body in which the fungi live or from beneath the soil to give support to the fungi for its growth and its survival.
