Question

Which of the following has the least affiliation with all of the others?
A) Glomeromycota
B) mycorrhizae
C) lichens
D) arbuscules

Accepted Answer

Lichens represent a symbiotic relationship between a fungus and a photosynthetic partner (usually an alga or cyanobacterium), which is distinct from the other options that are more directly related to the mutualistic relationships between fungi and plant roots (mycorrhizae, specifically arbuscular mycorrhizae involving Glomeromycota and arbuscules).
