The book emphasized on the details of practical knowledge and reduced the overwhelming number of new terms that usually appear in the text. In place of that, authors substituted more of the process of science. The book emphasis on scientific process involves explaining botany as botany is done. Specifically, author describe the competing hypotheses that botanists have devised to answer questions about botanical phenomena, the experiments done by botanists to test these hypotheses, interpretations of data, and the many unanswered questions and unresolved conflicts that remain. This approach differs significantly from that of merely presenting definitions and the conclusions of experiments.'
