Levels of Detail

Biology is a vast subject. There are many levels of detail that one can cover even within an introductory biology class. In order to make it easy to judge the level of detail covered, the text pages are color coded by difficulty level. Green pages should be easily understood by young or casual readers. Orange pages require a bit of background knowledge. Purple pages are designed for college level students. The pages are marked on the index by colored leaves, and on the pages by a solid bar across the top of the page.
