What group of fungi has the ability to penetrate its host's cell wall, thus increasing the efficiency with which materials are passed from fungus to host?

Question

Quizplus · Accepted Answer

Arbuscular mycorrhizal fungi have specialized structures called arbuscules that allow them to penetrate the cell wall of their host plant. This increases the efficiency of nutrient and material exchange between the fungus and the plant. Ectomycorrhizal fungi form a network of hyphae around the plant cells, but do not penetrate the cell wall. Endophytes are fungi that colonize plant tissues without causing harm, but do not necessarily increase nutrient exchange efficiency. Lichens are symbiotic associations of fungi and algae or cyanobacteria, and do not necessarily have specialized structures for penetrating host cells.
