White spruce is a medium-sized tree found in northeastern United States and throughout Canada. White spruce has a cone-shaped crown, and when grown develops a cone shape which extends nearly to the ground. This habit along with the spreading branches give it a nice appearance for use as a Christmas tree. Trees often reach 80-140 feet in height and 1.5 to 3 feet in diameter.
Leaves (needles) are needle-shaped, and are often somewhat crowded on the upper half of the branchlets. Needles are usually 1/2 to 3/4 inch long, blunt at the tip and green to bluish-green in color. The bark is thin, light grayish-brown and is produced in irregular, thin, scaly plates.
In the picture, we can see the thin wall separating the outside air from the stoma and chloroplast. We can see the chloroplast as well which are the objects outlined by the black lines. We can also see the stroma which is the watery medium that surrounds the chloroplast. The stroma is the place where the Calvin cycle takes place as well. This is what we see inside the White Spruce Leaf. The White Spruce tree is a hydrophilic tree/plant.
