Tree Basics
|
|
Trees are generally split into two broad groups: gymnosperms and angiosperms. Gymnosperms are a taxonomic class that includes plants whose seeds are not enclosed in an ovule. The word gymnosperm when translated actually means "naked seed".

| Gymnosperms include most evergreen species such as pines, spruces and firs. Some gymnosperms, including larch and ginkgo, do lose their leaves in the winter. Gymnosperms are often called "conifers" since many of them produce seeds in cones, as well as "softwoods" since many of them have softer wood. |
