Maple trees reproduce by shedding their twin seed pods, which are then dispersed in the wind before germinating where they land. These pods are called "helicopters" because the wind causes them to spin like the rotor on a helicopter as they drift gently down to the ground below.Continue Reading
Catching one of these helicopters and opening it up reveals a pair of seeds, connected by two wings that are so thin that they are almost undetectable. These seeds represent the fruit that comes from a maple tree.
The wings on the seed pods allow them to drift in the air longer, creating a wider dispersal zone from the parent tree. Once the pods hit the ground, they enter the soil through a number of processes, including the softening of the soil by the rain, having animals or people step on them and push them into the soil, and other environmental effects.
The maple tree thrives only in certain temperate zones. In North America, maples grow in southern Canada and portions of New England, including Pennsylvania, Massachusetts, Maine, Ohio, New Hampshire and Vermont. The reason for this limited growth area is that nighttime and daytime temperatures have to fall within a certain range year-round. Also, the formation of frost is crucial in the development of the maple tree.Learn more about Botany
Humans manufacture thousands of products from trees, in addition to cultivating fruits and nuts from the arboreal life forms, explains the Idaho Forest Products Commission. Byproducts of papermaking are used in chewing gum, asphalt, turpentine, paint and detergents. Cellulose fibers are raw materials for toilet seats, helmets, toothbrushes, dinnerware, nail polish and industrial explosives.Full Answer >
A tree breathes through its leaves using chlorophyll, the substance that makes leaves green. Chlorophyll absorbs the carbon dioxide in the air and uses it alongside water to break down minerals absorbed through the tree's roots. The leaves then release water vapor and oxygen.Full Answer >
Conifer trees go brown because of pests, diseases or unfavorable growing conditions, such as drought, frost and cold winds. Cypress aphid is a common pest that causes conifer browning. It could also sometimes be caused by mistakes in trimming routines like over-trimming and trimming at the wrong time of year.Full Answer >
Identify hickory trees by inspecting the leaves for certain characteristics, such as serrated edges and an alternating pattern of leaf shapes and sizes. A single hickory leaf stalk, or rachis, can possess anywhere from five to 17 leaves.Full Answer >
