Which of These Paired Fungal Structures are Structurally and Functionally

Question

Which of these paired fungal structures are structurally and functionally most alike?
A)conidia and basidiocarps
B)sporangia and hyphae
C)soredia and gills
D)haustoria and arbuscules
E)zoospores and mycelia

Accepted Answer

Haustoria and arbuscules are similar structurally and functionally. Both are specialized structures that form in the hyphae of certain fungi to allow for nutrient uptake from the host plant. Haustoria are found in some parasitic fungi and form a specialized attachment to the host plant's cell wall, while arbuscules are found in mutualistic fungi known as arbuscular mycorrhizae and form a branching network within the host plant's root cells. The other structures listed have different structures and/or functions.
