Which of the statements about mycorrhizae is correct? Endomycorrhizal fungi branch extensively in the soil surrounding plant roots, whereas ectomycorrhizal fungi do not. Endomycorrhizal fungi constitute a monophyletic group. Endomycorrhizal fungi provide plant roots with nutrients, whereas ectomycorrhizal fungi do not. The hyphae of ectomycorrhizal fungi penetrate plant root cells. Endomycorrhizal fungi receive carbohydrates from plants, whereas ectomycorrhizal fungi do not.

One major difference between ectomycorrhizae and arbuscular mycorrhizae is most ectomycorrhizae are zygomycetes while most endomycorrhizae are basidiomycetes. ectomycorrhizae do not penetrate plant roots; arbuscular mycorrhizae penetrate plant roots. ectomycorrhizae are parasitic on plant roots while arbuscular mycorrhizae are not. ectomycorrhizae form mutualisms while arbuscular mycorrhizae are parasitic. ectomycorrhizae are more common on plant roots than arbuscular mycorrhizae.

Which of the following statements about the hyphae of ectomycorrhizal fungi are correct? I. They provide plants with minerals and water from the soil. II. They rely on sugars that plants produce by photosynthesis. III. They grow between root cells. The hyphae don't penetrate into root cells. I and III only.
The Greek root ecto means "outer." Why are ectomycorrhizal fungi or EMF, aptly named? a. Their hyphae form tree-like branching structures inside plant cell walls. b. They are mutualistic. c. Their hyphae form dense mats that envelop roots but do not penetrate the cell walls. d. They transfer nitrogen from outside their plant hosts to the interior
