Study Notes
Unifying Themes in Biology
- All organisms share key characteristics
- Composed of one or more cells, the fundamental unit of life; single-celled organisms are common.
- Require energy sources for life processes, from chemical energy.
- Respond to environmental stimuli; react to light, temperature, touch.
- Reproduce and pass genetic material (DNA); crucial for species continuation.
- Develop and change throughout their lifecycles.
Interconnected Systems
- Life at all levels (cells to ecosystems) is organised into systems.
- Systems consist of interacting parts, each crucial for the whole.
- Examples: cells forming tissues, tissues forming organs, and organs forming organ systems.
Structure and Function
- Structure strongly influences organism function.
- An organism's body plan relates to its role and environment.
- The webbed foot of a duck, for instance, suits its aquatic lifestyle, aiding in swimming and foraging, as opposed to the feet of birds who perch.
