(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…

9. Label the sporangia, indusium, leaf, and spores in Figure 4 below. 01 Figure 4. Cyrtomium leaf c.s., sorus l.s. 10. Explain the mechanism of spore dispersal in ferns with sori 11. In what way is this mechanical method of spore dispersal similar to that in the bryophytes? Photo by Carolyn Alling Most ferns produce only one kind of spore and are therefore homosporous. Upon germination, the spore, the first cell of the gametophytic generation, gives rise to a heart shaped, bisexual gametophyte, called a prothallus. 12. What type of nuclear division produces the many celled gametophyte from a spore? Examine the fern gametophytes under the dissecting scope. Note the many rhizoids emerging from the lower, or ventral, surface. Among the rhizoids you will find antheridia, some of which may contain sperm cells. Nearer the notch of the "heart" you will find the archegonia. In order to visualize their shape in three dimensions, you will have to focus up and down on the archegonia. Examine the…

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.
