Trees are a perennial wood plant which typically has many secondary branches supported and lifted clear off the ground by a central main stem or trunk. The insides of trees contain woody tissues for strength and vascular tissue to carry nutrients from one part of the tree to another. Most trees are surrounded by a layer of bark which serves as a protection barrier. Below the ground, roots branch and spread out widely, serving to anchor the tree in place as well as extract moisture and nutrients from its environment. Trees typically bear leaves (or needles) which contain chlorophyll and convert energy from sunlight, as is typical of most plants.

Trees are used by humans in many ways, but mostly as a food source from the fruits they bear, as well for building materials from lumber. The sap or resin from trees is also processed and used to make various chemical preservatives, such as varnishes. Dried lumber and tree branches are also used as fuel for making fire, which provides for warmth and cooking. Even the bark of certain tree species is used, for example the spice cinnamon is made from the bark of the cinnamon tree, and the medicine, aspirin, is made from the bark of the willow tree.

Connecticut, like other parts of New England, is famous for our deciduous tree forests, especially in the autumn, when the leaves turn a variety of colors including bright yellows, reds and oranges. Maple syrup, made from the sap of maple trees is also a local favorite and used as a topping for pancakes and waffles in most of the United States. Connecticut also has an abundance of fruit trees and orchards, and apple picking is a favorite autumn activity.
