Evolution of Plants Adam Christensen

Plants are varied for the same reason that animals are, they became varied after years of evolution. Evolution caused change in things such as the leaves on the tree or where the branches start splitting from the trunk on trees.

Plants evolved in similar ways that the animals evolved. Factors such as how easy is it to get water, or long can the plant survive without sunlight.

Some estimates put the first plants appearing over 630 million years ago. They were very simple plants and had little roots, once animals and other factors were added they had to evolve in order to survive and they developed bigger and deeper roots, and other ways to survive like thorns.

Flowers are actually a result of evolution and the earliest plants didn't have flowers on them.
