Study Notes
Unifying Themes in Biology
- One of the major unifying themes in the field of biology is the concept of cells as the basic units of life.
Organization of Life
- All organisms are made up of cells, which are the fundamental units of life.
- Cells are the basic structural and functional units of life, and all living organisms are composed of one or more cells.
Cellular Functions
- Organisms are able to move, grow, and reproduce due to the ability of cells to perform various functions such as metabolism, response to stimuli, and reproduction.
Levels of Organization
- Biologists can study life at various levels of organization, including:
- Molecular level (e.g. genes, proteins)
- Cellular level (e.g. cell structure, function)
- Organismal level (e.g. physiology, behavior)
- Population level (e.g. ecology, evolution)
- Ecosystem level (e.g. interactions between organisms and environment)
Scientific Method
- Biologists use observations and questions to make predictions, design experiments, and draw conclusions.
- The scientific method allows biologists to study life and develop a deeper understanding of biological phenomena.
