- (rather than herbaceous) in that the xylem often displays secondary growth (widening of the trunk). They generally have only tracheids for water conduction and lack vessel elements, which are characteristic of angiosperms. Tyino I. Division: Cycadophyta Although there is only about 100 extant species of cycads, this phylum was significant during the Triassic period (248 million years ago). They are tropical and subtropical plants with trunk-like stems and compound leaves and are popular as ornamentals. These plants are dioecious in that seed cones and pollen cones are on two separate plants. Because of their palm-like structure, they are sometimes incorrectly described as palm trees. However, like other gymnosperms they produce cones and lack flowers. Examples of cycads include False king sago and Florida coontie (Zamia pumila). Zamia pumila is the only cycad native to the United States. ACTIVITY 1: Examine the live plant and/or cones if available. (Use the atlas if necessary.) olsmot…The classification of the seed plants has varied. If a person groups all seed plants together in one large Division Spermatophyta, then they have two classes—the class with naked seeds and the class , plants with carpels. On the other hand, many people (and this book) use four divisions, not one. List the three divisions of “gymnosperms” and the one division of flowering plants.Complete this table: Comparison of Important Characteristics of Land Plants Features Moss Fern Conifer Flowering Plant Gametophyte or sporophyte dominant Gametophyte Sporophyte Vascular tissue (+/-) No vascular system Seed (+/-) No seeds Fruit (+/-) Water required for fertilization Pollen grain (+/-) Homosporous or heterosporous Homosporous Homosporous Heterosporous Heterosporous Examples
