In this aid, we attempted to present the theory of the school book in the most understandable way possible. Therefore, we used more than 300 color images and diagrams to give the student a visual representation of what is mentioned in the school manual and cannot be seen, making it easier to memorize. Also, for the first time in a biology book, we incorporated small QR codes that guide students to educational videos related to the corresponding part of the theory, helping them to understand it even better. We also provide many supplementary pieces of information that further analyze some difficult parts of the material or answer questions that may arise for the student while reading the school book. These pieces of information are auxiliary and in no case do we suggest that the student memorize them.
