A core text for those studying A Level Biology. Divided into five main parts, the book encompasses topics from basic cell biology to the impact of Man. The author has focused on the logical development of key ideas, by beginning each chapter with material which the student should already be familiar and building up gradually to the more difficult concepts. Each chapter begins with a Learning Objectives box outlining the main topic areas to be covered and finishes with questions of increasing difficulty, designed to test the student's understanding of the topic. Additional Information Boxes expand on ideas covered within the main text, while the Clear Thinking Boxes attempt to address common misapprehensions in biology.
