What Is a Spruce Tree?
A spruce tree is a coniferous evergreen tree that comes from the species Picea. There are approximately 35 different species of spruce trees that grow within the northern hemisphere. These coniferous evergreens are known to live to a very old age and can grow extremely tall, sometimes reaching heights of 200 feet (60.96 meters). A spruce tree is called a coniferous evergreen because its needles stay green all year round and it bears cones that grow on the ends of the branches. The different types of spruce trees include the Norway spruce tree, the blue spruce tree, the white spruce tree and the black spruce tree. Spruce trees can be found in dwarf versions as well. A dwarf spruce tree tends to grow slower and reach heights no taller than eight feet (2.44 meters). Spruce trees may differ in color from one specimen to another. For instance, the blue spruce shows off a silver-blue color in its needles while the Norway spruce bears a deep, bright green color. The white spruce is known for
More to the point, what is a tree? In essence, a tree is a living machine that generates energy in order to feed its need to be taller than everything around it. A forest in its natural state is a set of different canopies trying to compete with each other for light, their roots reaching out for nutrients and water; all the time at the mercy of the landscape and the weather. The tallest trees are tremendously heavy, their trunks bound into columns of woody tubes that carry water upwards to the leaves where it takes its part in the photosynthetic process the conversion of carbon dioxide and water into sugars that the tree uses to build itself; leaf, twig, root and trunk. Photosynthesis is common to all plants. As with phytoplankton, the energy used by the tree comes from the sun; and the by-product is oxygen. Along with their crucial role in building and stabilising topsoil, providing habitats for countless species and moistening the air around them; a waste gas liberated from them thro
