Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Explain how angiosperm diversity is due, in part, to multiple complex interactions with animals
Describe ways in which pollination occurs
Discuss the roles that plants play in ecosystems and how deforestation threatens plant biodiversity

Meet ethnobotanist Ina Vanderbroek in these videos from NOVA's "The Secret Life of Scientists & Engineers." Ina studies how people use medicinal plants for healing. She explains how she creates a guidebook of the plants to help doctors treat their patients better. The TV series Star Trek influenced her to become a scientist. In her spare time, she enjoys salsa dancing.
