Study Notes
Fundamental Units and Characteristics of Life
- All organisms are composed of cells, which are considered the basic structural and functional units of life.
- Genes serve as the fundamental units of heredity, instructing organisms on how to grow, develop, and function.
Unifying Themes in Biology
- One major unifying theme in biology is the concept of evolution, which explains both the unity and diversity of life forms.
- Biological systems exhibit organization at various levels, from molecules and cells to communities and ecosystems.
Biological Processes
- Organisms rely on energy and matter to facilitate movement, growth, and reproduction, essential processes for survival.
- Biologists use the scientific method to observe phenomena, formulate questions, and hypothesize solutions.
Levels of Biological Organization
- Life can be studied at multiple levels of organization: molecular, cellular, tissue, organ, organismal, population, community, ecosystem, and biosphere.
