tree leaf identification nc New Study Reveals Unexpected Leaf Patterns - Away State Journal
Leaves make food for the tree, and this tells us much about their shapes. For example, the narrow needles of a Douglas fir can expose as much as three acres of chlorophyll surface to the sun. The lobes, leaflets and jagged edges of many broad leaves have their uses, too.

Trees live out their lives in surprising ways, massive new study finds
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. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods.
In this article, you will learn how to identify many different types of trees. Most of these trees are common in North America, Europe, and other countries around the world. All of the thousands of species of trees fall into two categories – deciduous trees and evergreen trees.
A tree is a woody plant that regularly renews its growth. Most plants classified as trees have a single self-supporting trunk containing woody tissues, and in most species the trunk produces secondary limbs, called branches.
