Branches of Biology 2026
Branches of Biology Biology, derived from the Greek words bios (life) and logos (study), is the vast and dynamic science that explores the living world. From the microscopic machinery inside a cell to the complex interplay of ecosystems, biology seeks to understand the principles governing all life forms. Given the staggering diversity of life—from bacteria to blue whales, from fungi to forests—the field has naturally specialized into numerous branches. Each branch focuses on a specific level of organization, group of organisms, or set of processes, creating a comprehensive map to navigate the wonders of life. Foundational Branches Based on Scale and Core Focus These branches form the bedrock of biological study, defined by their scope and fundamental questions. 1. Molecular and Cellular Biology This branch delves into life at its most basic level. Molecular Biology focuses on the structure and function of the essential macromolecules of life: DNA, RNA, and proteins. It unravels the…
