What is the thread-like material that makes up the vegetative structure of fungi called?

The thread-like material that composes the vegetative structure of fungi is known as hyphae. Hyphae are long, filamentous structures that grow and branch out to form a network. When a mass of hyphae gathers, it creates a structure called mycelium, which is the main body of the fungus. Mycelium plays a crucial role in nutrient absorption and growth.

While mycelium represents the collective network of hyphae, the individual thread-like components are specifically referred to as hyphae. This distinction is important in understanding the development and functioning of fungi, as hyphae contribute to their structure and the processes of decomposition and nutrient cycling in ecosystems.
