Study Notes
Unity and Diversity of Life
- The central theme in biology, explaining both unity and diversity, is evolution.
- Evolution accounts for how different species arise from common ancestors, leading to vast diversity while sharing many biological traits.
Major Themes in Biology
- Major themes include evolution, homeostasis, structure and function, energy and matter, information flow, and systems of organization.
- Characteristics like metabolism, reproduction, and adaptation also showcase these themes.
- Factors like environmental adaptation do not constitute a primary theme in biology.
Primary Unit of Structure and Function
- The cell is the fundamental unit of structure and function in all living organisms.
- All organisms are composed of one or more cells, highlighting the cell's essential roles in biological processes.
Processes of Life
- Metabolism encompasses the biochemical processes that allow organisms to move, grow, and reproduce.
- Energy utilization, cellular respiration, and reproduction are central aspects of metabolism.
Scientific Method in Biology
- Biologists employ the scientific method, which includes observation, hypothesis formation, experimentation, and conclusion.
- This systematic approach enables the exploration, understanding, and explanation of biological phenomena.
