Revised and updated to reflect the most recent AP Biology test, this set of 450 flash cards covers 20 general categories: About the AP Biology Exam, Biochemistry, The Cell, Cell Division, Cell Respiration, Photosynthesis, Heredity, Molecular Genetics, Biological Diversity, Evolution, Plants, Endocrine System, Immunology, Nerves & Muscles, Reproduction & Development, Ecology, Animal Behavior, Lab Introduction, Lab Review, and Multiple-Choice Questions. New to this edition are introductory cards that describe the AP Biology exam in detail and 50 multiple-choice question cards for added practice. Words that frequently occur on the exam appear in blue, while important terms and phrases that students are advised to memorize appear in bold type or italics. Although designed primarily as an Advanced Placement test study aid, these flash cards can be used by all biology students. They are especially useful when used as a study aid in tandem with Barron's AP Biology test prep manual.
