CHAPTER OVERVIEW:

Chapter 27 - Origin and Diversity of the Eukaryotes.

In this chapter, we continue our survey of the diversity of life, focusing on the Eukaryota. Chapter 27 provides an overview of the Eukaryotes, including a discussion on the climatic changes that allowed this group of organisms to emerge, major characteristics

The chapter begins by describing the emergence of eukaryotic cells  - Chp 27.1 – read this section carefully. Know and understand the necessary steps in this development.

- Nextt, the authors describe the characteristics of five major groups of protists; also the ecological importance and evolution of various reproductive strategies – Chp 27.2  -skim this section, paying special attention to the parts describing the pertinent learning objectives.
- Chapter section 27.3 discusses the relationship between sex and reproduction in protists – read this section carefully.
- Finally, Chp 27.4 describes the effect of protists on the environment – read this one, too.

Chapter 28 - Plants without Seeds: from Water to Land.

In this chapter (Chapter 28 - Plants without seeds) we explore the transition of plant life from and aquatic to a terrestrial environment.

- The first section of this chapter (28.1) describes our best understanding of the emergence of photosynthesis, the clades of algae where photosynthesis first appears, and their relationship to land plants. Read this section focusing on the information that would allow you to answer the questions in RECAP 28.1 (pg 573).
- Read Section 28.2 thoroughly. This section describes the adaptations that facilitated the transition to land. In lab next week, we'll be examining representative species demonstrating the acquisition of a few of these traits.
- The final section (28.3) rounds out the chapter, describing features that developed which contributed to the diversification of plant body form. Read carefully - lots of interesting information here.

EUKARYOTES:

- This article (http://evolution.berkeley.edu/evolibrary/article/history_24 (Links to an external site.)) discusses a bit about the observation that lead Dr. Lynn Margulis to develop the theory of endosymbiosis of some organelles in Eukarya AND some of the genetic evidence supporting this idea!

- Endosymbiosis described by one of my favorite video people (Paul Anderson - Bozeman Biology)  -

SEEDLESS PLANTS:

- Bryophytes, the secret plants that surround us  This bilingual video offers a fascinating insight into the world of bryophytes.  Do not fear, when French spoken is subtitled!  :-)
