Modern biology is a fascinating but complex, multifaceted science. And the school textbook Biology. Grade 9 is a valuable guide to the world of knowledge about it. The structure of the book is as follows: nine topics are divided into 55 chapters, the content of each chapter is 2 (min) or 4 (max) pages, and the total volume of the textbook is 256 pages; the placement of chapters is strictly structured - each begins on a new (odd) page; all figures, diagrams, tables, and photographs are functional. Figures are placed at the bottom of the same page where they are referenced in the text of the paragraph. Thus, students work through part of the content of the paragraph immediately while studying it, perceive new information step by step and analyse it.

Tasks with appropriate labels are offered for the illustrative material:

the student performs the task independently;Pupils discuss problems in a group, formulate conclusions, make certain judgements.

In the textbook Biology. 9th grade, the reproductive and creative tasks of the "Repeat, Think" section at the end of the paragraphs will provide a repetition and generalisation of what has been learned.

The test tasks of the section "Self-Control of Pupils' Learning Achievement" for each topic are differentiated by cognitive levels and level of difficulty. They are presented in the format of EIT and in the form of open-response tasks. The implementation of laboratory research, laboratory and practical work, and student projects is carefully developed step by step.

Each of the nine topics begins with the section "From the History of Discoveries", the information of which is intended to prepare students to understand the importance of this branch of biology, the history of its emergence, to acquaint them with the names of prominent world scientists and their discoveries.
