ADVANCED BIOLOGY. By Mary Jones and Geoff Jones. Cambridge University Press #163;23.50
Advanced Biology covers the core of A and AS-level syllabuses and has much material that is relevant to the optional components as well.
It is straightforward with interspersed colour-coded boxes - purple for the introduction and questions related to sections of text, and blue for topics that are more difficult or not likely to be required by every syllabus.
But it is the quality and variety of the illustrations that make this full-colour textbook outstanding. Among the best are the drawings of animal and plant cells next to their electron micrographs. They are of identical magnification which help students interpret specimens.
Difficult concepts of water potential and related phenomena are presented with some originality - visual images are often combined in an explanation.No book at this level is complete without sample exam questions and this one doesn't disappoint. All in all, this is an impressive addition to an ever-growing list of useful books for post-16 courses.
