Emphasizing natural selection and incorporating the analysis of botanical phenomena and diversity into every subject, the new edition continues to encourage students to participate in biological inquiry. Among the many new pedagogical features are chapter summaries at the beginning of each of the books four sections (plant structure, plant physiology and development; genetics and evolution; and ecology); and boxes which highlight how plants interrelate with human concerns, such as medicine and economics. 9.25×11.
