CHAPTER OVERVIEW:

Chapter 29 - The Evolution of Seed Plants.  This chapter explores the evolution of seed plants.

- The first section of this chapter (29.1) describes various innovations that allowed the colonization of terrestrial habitats further removed from water, including the development of seeds and woody stems. A thorough description of the seed follows a description of the life cycle of seed plants. Read this section carefully focusing on the information that would allow you to answer the questions in RECAP 29.1 (pg 592).
- The following section (29.2) describes the characteristics of the earliest of seed plants - the gymnosperms. Perhaps the most important feature of these plants is that sperm have lost the ability to swim, they're no longer tied to water for fertilization. While interesting, the rest of the section goes into more detail than we'll focus on this semester. So,skim this section thoroughly.
- The next section (29.3) discusses the importance of flowers and fruits to the success of angiosperms - the dominant plant life form today. Read this section thoroughly. SO much interesting information in this section. An especially interesting story is the evolution of carpels and stamens form leaf-like structures! In lab Tuesday, we'll be examining representative specimens of flowers and fruit, along with the reproductive structures of the seedless plants.
- The final section (29.4) rounds out the chapter, describing various ways in which plants benefit humans. While interesting, skim this section. It provides a general overview of the importance of plants to humans. For a more thorough understanding of the relationship, you will have an opportunity to view and comment on a film for extra credit. Details to follow.
