Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight.

A tree is a plant form that can be found in many different orders and families of plants. Trees show many growth forms, leaf type and shape, bark traits and organs. The tree form has changed separately in classes of plants that are not related, in response to similar problems (for the tree).

Two main opposing forces affect a tree's height; one pushes it upward while the other holds it down. By analyzing the interplay between these forces in coast redwoods (Sequoia sempervirens), a team of biologists led by George Koch of Northern Arizona University calculated the theoretical maximum tree height or the point at which opposing forces balance out and a …
