What is the primary role of a mushroom's underground mycelium?

Question

Quizplus · Accepted Answer

The underground mycelium of a mushroom primarily absorbs nutrients from the surrounding soil, allowing the mushroom to grow and mature. Anchoring may play a secondary role in supporting the structure of the mushroom, but absorbing nutrients is its main function. Sexual and asexual reproduction occur in the fruiting body of the mushroom, not in the mycelium, and protection is not a primary role of the mycelium.
