Which of these paired fungal structures are structurally and functionally most alike?

Question

Quizplus · Accepted Answer

Haustoria and arbuscules are both specialized structures that allow fungi to obtain nutrients from their host plants in a symbiotic relationship. Haustoria are invasive structures that penetrate the host plant's cell wall and allow the fungus to absorb nutrients directly from the plant cell. Arbuscules are branch-like structures that penetrate the root cell wall but not the cell membrane, creating a mutually beneficial exchange of nutrients between the plant and fungus. Conidia and basidiocarps are both involved in reproduction but are structurally and functionally different. Sporangia and hyphae are also structurally different, with sporangia producing spores and hyphae forming the body of the fungal organism. Soredia and gills are also different, with soredia being small clumps of hyphae and algae that can break off and colonize new habitats and gills being structures on the underside of some fungal fruiting bodies that release spores. Zoospores and mycelia are also different, with zoospores being motile spores that use a flagellum for movement and mycelia being the vegetative part of the fungal organism that consists of intertwined hyphae.
