Teaching cell biology can be a daunting task because the field is so vast and rapidly moving, characterized by a continual explosion of new information. The challenge is how to teach students the fundamental concepts without becoming bogged down in details. Students need to understand the principles of cell biology and be able to appreciate new advances, rather than just memorizing "the facts" as we see them today. At the same time, the material must be presented in sufficient depth to thoughtfully engage students and provide a sound basis for further studies. The Cell, Seventh Edition, provides a balance of concepts and details that meets the needs of today's students and their teachers. Written by an active scientist and experienced educator, this textbook combines readability and cohesiveness with comprehensive and up-to-date science.
