They have true roots, stems, and leaves. Their vascular system is complex and wide spread. Besides allowing them to conduct water and nutrients long distances they provide support that allows the plants to grow up to 400 feet tall. However, another adaptation to life on land that is unique to this group is the ability to produce seeds. These structures are multicellular organs with specialized structures to insure survival of the seed.
Seed coats prevent drying out and the cotyledons provide nutrients for the growing embryo.
The seeds will be found either in cones or flowers. Cones are typically found in a group called the Gymnosperms which, while not a legitimate taxonomic category, is a term used for all plants bearing seeds in cones. Those plants in which the seeds are carried in flowers are called the Angiosperms. For this portion of the exercise you will be using the Interpretive Garden Location Maps and the Interpretive Garden Plant Lists. Using the Plant List, locate a plant fitting the category requested and record the number alongside it.
