In the plant kingdom, all of the species are descended from a single common ancestor. in terms of phylogeny, what type of tree of life is this?

monophyletic tree

Explanation:

A monophyletic tree is when a group of organisms descended from a single ancestor like in the example given. In the image I added you can observe that there are also paraphyletic (showing the most recent common ancestor, but not all of its descendents like monophyletic trees) and polyphyletic trees (unrelated organisms descended from more than one ancestor).

I hope you find this information useful and interesting! Good luck!

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
