The material covers a wide and integrated range of topics in modern biology, including evolutionary biology, comparative anatomy, plant and animal systems, ecological principles, embryology, biodiversity, and environmental science. Key areas include the origin and classification of life, plant anatomy and reproduction, tissue types and organ systems, homeobox genes, ecosystems and biomes, and the role of biodiversity in environmental balance. Students will also find thorough insights on genetics, developmental biology, natural selection, scientific methodology, phylogeny, and major ecological concepts such as niches, symbiosis, succession, and energy flow. The guide addresses essential scientific figures, landmark theories (such as the endosymbiotic theory), environmental activists, and modern challenges in conservation and sustainability. It integrates human anatomy and physiology, biogeochemical cycles, and even topics like bioinformatics and genomics, giving students a truly interdisciplinary review experience. This resource is especially beneficial for students in general biology, environmental science, ecology, life sciences, anatomy and physiology, and pre-medical or pre-veterinary programs. It's ideal for exam preparation or in-depth revision of both plant and animal biology concepts across multiple systems and levels. Keywords: evolution, biodiversity, ecosystems, anatomy, plant biology, tissues, organ systems, mesoderm, ecology, embryology, comparative anatomy, genetic variation, energy flow, scientific method, homeobox genes, niches, symbiosis, natural selection, conservation, biogeochemical cycles, plant tissues, vertebrates, LSUE
