The work of the Hungarian authors with decades of educational experience is not a lexicon, but rather an encyclopedia divided into chapters, which includes elementary and secondary school knowledge, but at the same time contains far more than the high school biology curriculum. More than 1,500 diagrams help to understand the information formulated with professional sophistication and in an easy-to-understand style. Navigating through the volumes is facilitated by the index, which contains approximately 5,500 headings.
The book covers the most important theoretical (biochemistry, systematics, organization, physiology, microbiology, ecology, genetics, evolution, ethology) and applied subfields of biology (health, medicine, crop production, animal husbandry, environmental and nature conservation, protected plants and animals), while it affects the physical and chemical foundations necessary for their understanding. The structure of the volumes also reflects the structure of the specialty: starting from the basis of atoms and molecules, it reaches the biosphere, the highest organized biological level. The topics are introduced by a rich overview of the history of science.
It can be a useful tool for all biology teachers, interested elementary school students and especially high school students. It can be especially recommended for high school students preparing for the advanced level matriculation exam and intending to continue their studies at university, and it can also be used effectively by university students.
