Gymnosperms | Tree Biology + Tree ID

Non-vascular plants are simple plants that move water and sugars cell-to-cell. Vascular plants are more sophisticated, with a dedicated transport system called the vascular system. One of the major groups of vascular plants is the gymnosperms. They are distinguished from the other major group (angiosperms, the flowering plants) by their "naked seeds" - these are not surrounded by a fruit. Within the gymnosperms, conifers (cone-bearing plants) make up the largest group. Other gymnosperms that an arborist may work with include cycads and ginkgos, both of which are ancient trees. Terminology covered: gymnosperm, angiosperm, conifer, vascular plant
