How does it apply to the fungi? a. Monophyletic refers to organisms that arose from a single common ancestor. Fungi are thought to be monophyletic, arising from a common ancestor with oomycetes (water molds) and myxomycetes (slime molds). 3) Explain how fungi obtain nutrients from the environment? a.
