A single sheet of 8 1/2-inch by 11-inch notebook paper weighs roughly .16 ounces. An envelope weighs slightly less than that. This means that four pieces of notebook paper and an envelope can be comfortably mailed using only one stamp, and five sheets of paper may even still stay under the 1-ounce limit.
Defined as plants that retain their leaves year-round, evergreens add a bright spot of color to a winter landscape. Conifers, like pine, spruce, cedar and fir are what typically come to mind when we think of evergreens but magnolia, hollies and eucalyptus trees are also evergreens.
In botany, an evergreen tree type or plant is a plant that has leaves in all seasons. This contrasts with deciduous tree type or plants, which completely lose their foliage during the winter or dry season.
