Study Notes
Unity and Diversity of Life
- A major theme in biology is the explanation of the unity and diversity of life
- This theme unifies biology as a single, coherent field
Cellular Basis of Life
- The shared characteristic of cells as the basic unit of life unifies biology
- Cellular structure and function allow organisms to move, grow, and reproduce
Levels of Organization
- Biologists study life at multiple levels of organization, including:
- Molecules
- Cells
- Organ systems
- Organisms
- Populations
- Communities
- Ecosystems
- Biosphere
Subdisciplines in Biology
- Biologists define subdisciplines within biology based on:
- Scale of organization
- Types of organisms
- Biological processes
- Specific techniques or approaches
