Study Notes
Unity of Biology
- Biology is unified by the principles of cellular organization, genetic information transfer, and evolutionary processes.
- All living organisms share common functions such as metabolism, growth, and reproduction.
Major Theme in Biology
- Evolution by natural selection serves as a central theme that explains both the unity and diversity found in life forms.
- This process illustrates how species adapt over time leading to biodiversity while retaining fundamental similarities.
Organism Functions
- Organisms possess cellular structures that enable movement, growth, and reproduction.
- Processes such as cellular respiration, division (mitosis), and reproduction (sexual and asexual) are essential functions for life.
Levels of Organization
- Biologists examine life from molecular to ecological levels, utilizing a reductionist approach that involves studying systems in smaller, manageable parts.
- Different levels include molecules, cells, tissues, organs, organisms, populations, communities, ecosystems, and the biosphere.
Observation and Inquiry
- Biologists employ various tools such as microscopes, field studies, and laboratory experiments to make observations of biological phenomena.
- Formulating questions is often guided by hypotheses which subsequently lead to experiments and data collection for analysis.
