Trees, Season, Leaves

    In the Dunn Woods Field Experience, I learn about the season affect trees and how to identify the type of trees. As we know, there are four season in a year. But, with the change in temperature, the trees will be grow. In Spring, Summer, and Fall trees grow up so fast and in Winter trees almost dormancy. The  leaves sprout in Spring, in summer  leaves can carry on the photosynthesis and make carbohydrate to supply the tree grow. In  autumn, most of trees are yield fruits. In winter, all leaves fall off, except, coniferous trees. There are countless type of trees in the earth. As a student, we need know some general trees variety. I think that my tree is part of  frigid zone plant. Because, in winter my tree's leaf can't fall off. Next time, I will go on study about category of the tree.
