Book Description: The Science of Agriculture: A Biological Approach, third edition helps students bridge the gap between biological concepts and their applications. The text concentrates on the scientific principles, or the "why" behind the industry. Topics such as plant and animal systems, soils, cell functions, genetics, genetic engineering, plant and animal reproduction, entomology, the uses of biotechnology, and careers are covered throughout the text. The text also includes a thorough examination of the controversy and concerns over the use of genetic engineering, genetically modified organisms, cloning, and their perceived and potential dangers to humans and the environment. Each chapter begins with clearly-stated learning objectives, followed by key terminology. Chapters close with student learning activities that extend learning beyond the text material. End-of-chapter test questions in True/False; Short Answer/Discussion; and Multiple Choice formats help to evaluate students' grasp of the concepts presented in the text.
