7 - Seed Plant Diversity

Labs 6 and 7 follow the evolutionary relationships among members of the Plant Kingdom, including their algal relatives. Lab 7 examines the plants that produce seeds. You should be able to classify these specimens into their respective phyla. As you look at these specimens and identify their parts, keep in mind the basic pattern of the alternation of generations and the changes that have occurred to allow plants to live on land. For example, in addition to identifying structure and function, ask yourself questions such as, "Is this structure part of a sporophyte or a gametophyte?“, “Are the cells haploid or diploid?” and "Are any of these structures adaptations to living on land?" As in all exercises, concentrate on those structures in bold face type and those that you were asked to label on your diagrams.
