Quizplus · Accepted Answer

Endomycorrhizal fungi constitute a monophyletic group, meaning they share a common ancestor and all of their descendants. This is in contrast to ectomycorrhizal fungi, which do not constitute a monophyletic group. The other statements are false: the hyphae of ectomycorrhizal fungi do not penetrate plant root cells, both endomycorrhizal and ectomycorrhizal fungi provide nutrients to plant roots, and both endomycorrhizal and ectomycorrhizal fungi receive carbohydrates from plants.
