D
Ascus
Verified step by step guidance
1
Step 1: Begin by understanding the role of each structure listed in the problem. Hyphae, basidium, mycelium, and ascus are all fungal structures, but their involvement in reproduction varies depending on the fungal group.
Step 2: Hyphae are thread-like structures that make up the body of fungi. They are involved in reproduction as they can form specialized reproductive structures or contribute to the formation of spores.
Step 3: Basidium is a microscopic structure found in Basidiomycota fungi. It is directly involved in sexual reproduction as it produces basidiospores.
Step 4: Mycelium is the network of hyphae that forms the vegetative part of a fungus. While it plays a role in nutrient absorption and growth, it is not directly involved in the reproductive process itself.
Step 5: Ascus is a sac-like structure found in Ascomycota fungi. It is directly involved in sexual reproduction as it produces ascospores.
