Study Notes
Unity and Diversity of Life
- The main theme explaining both unity and diversity in life is evolution, which showcases how organisms adapt and change over time while sharing common characteristics.
Essential Biological Processes
- Life processes that enable organisms to move, grow, and reproduce include metabolism, which encompasses all biochemical reactions sustaining an organism's life.
Fundamental Unit of Life
- All organisms are made up of cells, which are the basic structural and functional units of life, capable of carrying out all necessary life processes.
Levels of Biological Organization
- Biologists can study life at multiple levels of organization, including molecules, cells, tissues, organs, organisms, populations, communities, ecosystems, and the biosphere.
Research Methods in Biology
- Biologists utilize various tools and methods, such as microscopes, chemicals, and field studies, to make observations and pose scientific questions about living organisms and their environments.
