Study Notes
Unifying Theme in Biology
- Evolution is a central unifying theme, explaining the diversity of life through processes such as natural selection and genetic variation.
Basic Unit of Life
- The cell is recognized as the fundamental unit of life for all organisms, serving as the basic building block of biological structure and function.
Functions of Organisms
- Metabolism enables organisms to convert energy, allowing them to move, grow, and reproduce, maintaining homeostasis throughout their life processes.
Tools for Observation
- Biologists utilize various tools and technologies, such as microscopes and imaging techniques, to make observations and formulate scientific questions about living systems.
Levels of Organization in Biology
- Life can be studied at multiple levels, including molecular, cellular, tissue, organ, organismal, population, community, ecosystem, and biosphere levels, each providing different insights into biological processes.
