Botany is the branch of biology specifically dedicated to the study of plant life, including the properties, life phenomena, and classification of plants and plant groups. In contrast, zoology is the branch of biology that focuses on the animal kingdom, examining individual animals, populations, and their relationships to the environment.12

While these fields are traditionally separated for convenience of study, they are fundamentally interrelated. All branches of biology, including botany and zoology, share core biological principles such as cell division, reproduction, and the transmission of genetic material. Modern biological research emphasizes this structural and functional unity of life rather than just its diversity.32

Furthermore, biology is often organized by levels of study—such as molecular biology, cell biology, and population biology—which apply across both plant and animal sciences. Consequently, botany and zoology frequently overlap with other disciplines like ecology, biochemistry, and genetics to provide a comprehensive understanding of living organisms.34
