An easy-to-grasp introduction to cell biology, Essential Cell Biology has been carefully geared to introductory students, without any sacrifice of scientific rigor. The book's conceptual approach, in which the essential facts are presented in their biological context, is ideal for engaging and motivating students new to molecular and cell biology. The book is written especially for undergraduates in biological sciences, but its content can be easily understood and absorbed by advanced secondary school students who need a basic introduction to the essential topics in modern biology.
