- (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…Explain it by bullet. Division Cycadophyta: Cycads Internally, cycad stems are similar to those of seed ferns—a thick cortex containing secretory ducts surrounds a small amount of manoxylic (parenchymatous) wood. Unlike seed ferns, cycad foliage leaves do not bear ovules. Cycads produce seed cones and pollen cones, each on separate plants. Seed cones are variable, with those of Cycas revoluta usually considered the most relictual. Although Cycadophyta was a much larger group with many more species in earlier times,currently, it contains 9 or 10 genera and approximately 100 species.• They are almost all tropical with an unusual distribution; some occur in Cuba and Mexico, others in Australia, still others in southeast Asia or AfricaThe picture below is of a moss growing on my roof. It shows both the gametophyte and the sporophyte phases of the life cycle. Make a sketch and label which part of the moss is the gametophyte and which is the sporophyte. (Alternatively, you can find a live moss with both phases and take a picture, label it and upload here.) APR 25 étv J 280 MacBook Pro

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.
