Plant Biology With Infotrac - 9780534380618

PLANT BIOLOGY, Second Edition provides a complete introduction to the science of plants, combining the most current, real-world examples with information on plant biodiversity and ecology, including topics like biotechnology, economic botany, and plant/human interactions. PLANT BIOLOGY begins with elements of botany that are most familiar to students: the structure, function, reproduction, physiology, and genetics of flowering plants. The evolutionary survey is then presented, with detail on the Prokaryotes, Protists, Fungi, Bryophytes, early Tracheophytes, Gymnosperms, and Angiosperms. The overall sequence of subjects builds from metabolism and plant function to reproduction, then from simpler to more advanced organisms, concluding with two ecological chapters. Each chapter has been written in a modular fashion, however, to allow them to be taught in any order. In this new edition, the biodiversity chapters provide the best-supported, most current phylogenetic view of the organisms. Cladistics are introduced along with basic information, including gene sequences, followed by modern studies using cladistics and sequence information to identify natural plant groupings. Through this presentation, students can appreciate different types of evidence that describe the past events and directions of evolution. Ecology is another exciting area of study for the introductory student. Can photosynthesis by plants ease problems associated with the burning of fossil fuels? Can we stem biodiversity loss through better ecosystem management? Questions like these are addressed, making the text topical, readable, and a useful guide, all the while maintaining the length and language appropriate for beginning biology students.
