This full-color Photo Atlas guides you through the complex subject matter facing you in your lab course, whether it be biology, botany, or zoology. Unlike black and white atlases, Perry and Morton's comprehensive Photo Atlas presents more than 600 photographs in full color, so you get a true, clear picture of the material you're working on. This invaluable aid not only helps you grasp the material more quickly in a lab setting, but also enables you to recall later what you've seen in the lab. By covering up the labels associated with the photos, you can effectively use the Atlas to study and review for exams.
