Which structure in fungi is responsible for the production of spores?

The sporangium is a specialized structure in fungi that is primarily responsible for the production and release of spores. In many fungal species, the sporangium acts as a container where spores develop and are ultimately released into the environment. Spores serve as a means of reproduction and dispersal for fungi, allowing them to colonize new substrates and environments.

Hyphae are the filamentous structures that make up the body of the fungus and are involved in nutrient absorption. While they play an essential role in the overall life cycle and growth of fungi, they are not directly responsible for spore production. Mycelium, which consists of a network of hyphae, is important for the overall growth and health of the fungus but does not produce spores itself. Gametangium is involved in sexual reproduction, forming structures that generate gametes, but it is not the site for spore formation.

Thus, the sporangium is the correct answer as it is specifically adapted for spore production in fungi.
