Elaine Xiao's Lab 2 Journal

I chose to do the eastern white pine (Pinus strobus). They are native to eastern North America and are a large pine. It is also called the “Tree of Peace” or the “Weymouth Pine”. It is from the plantae kingdom, tracheophytes clad, pinophyta division, pinopsida class, pinales order, pinaceae family, pinus genus, p. subg. Strobus subgenus, p. sect. Quinquefolia section, p. subsect. Strobus subsection, and is the P. strobus species.

A general adaptation for all my observations is the thickness of the bark. I noticed most of my observations had large trunks and very thick barks to protect them through the cold winters of Montreal. These barks also help them adapt to the weather changes throughout the year.

The eastern white pine has a lateral root system that grows downwards. This adaptation is called sinker roots, and is different from the typical tap root. The sinker roots allow the system to have more surface area which allows the tree to take in more water for the rest of the plant.
