Trees

Lammy Nguyen and Eric Ceballos

Last week we had Kim educate us about tree identification. We played a competitive game among ourselves. We learned how to identify different type of trees by looking at their leaves and their bark by using a dichotomous key. We learned about the differences between coniferous trees and deciduous trees, but focused on deciduous trees.

Deciduous Tree need more energy to produce than coniferous trees which have needles, and they have seasonal leaf growth. Examples of deciduous trees are oak, maple, and ash trees.  Coniferous trees bear their needles all year long and their seeds are cone bearing.

We also learned about simple and compound leaves. Simple leaf has only a single blade and is join to its stalk to a woody twig. Compound leaf divided into 3 to several dozed leaflets. Leaflets are single blades that is attached by its stalk to the mid rib of the leaf.
