Vast underground networks of hyphae, called ____________ form the visible structures of most multicellular fungi. This increases their absorptive surface area, making the process of getting nutrients much more efficient.
Definition
mycelia (singular, mycelium)
Term
Fungi grow quickly at their _____________; thus, fungal growth is a result of increasing the length of the hyphae, not their circumference.

Definition
asexual
DNA
Term
If a spore enters the ____________ cycle, it germinates, producing hyphae that grow and eventually branch to form a mycelium, as in the asexual cycle.
