Fungi are made of bundles of threadlike ________.Group of answer choiceslichenshairchitinsmycelia

Fungi are made of bundles of threadlike mycelia. Mycelium is a crucial component of fungi, consisting of a network of hyphae, which are the long, thread-like structures that grow in the substrate. These hyphae absorb nutrients from the environment, allowing fungi to decompose organic matter and play a vital role in various ecosystems.

The other options do not accurately describe the structure of fungi:

• Lichens are symbiotic associations between fungi and algae or cyanobacteria, not the structure of fungi themselves.
• Hair is not a component of fungi but rather a trait of certain animals and humans.
• Chitin is a polysaccharide found in the cell walls of fungi, providing structural support, but it does not refer to the threadlike structures themselves.

Thus, mycelia correctly fills in the blank in the context of fungal structure.
