👉 Biology is the scientific study of life, encompassing the structure, function, growth, origin, evolution, distribution, and classification of living organisms. At its core, biology explains how cells, the basic units of life, interact and organize to form tissues, organs, and organ systems in multicellular organisms. Cells communicate through complex signaling pathways, regulate their internal environment via homeostasis, and undergo processes like mitosis and meiosis for reproduction and genetic diversity. Genetic information is stored in DNA, which directs cellular functions and is passed down through generations. Evolution, driven by natural selection, explains how species adapt and diversify over time. From molecular biology to ecology, biology integrates diverse fields to understand the intricate web of life on Earth.
