Structure and Function
Structure and Function
The way something is built (structure) determines what it can do (function).

Study Notes
Unifying Themes of Biology
-
Biology's unifying themes connect concepts from various fields.
-
All life levels have related component systems.
- A system is an organized, interacting group of parts.
- Cells are chemical/process systems.
- Body systems comprise interacting organs.
- Ecosystems unite living and nonliving things interacting.
-
Structure & function are intertwined.
- Structure dictates function; how something is arranged dictates its job.
- Protein structure directly influences function.
- Different protein structures mean different functions.
- Heart & stomach muscle cell structures & functions differ.
- Different species exhibit different anatomical structures with unique functions.
- Fibrous proteins (like collagen) are rope-like, providing strength & supporting tissues.
- Globular proteins (like hemoglobin) transport substances (e.g., oxygen).
-
Organisms maintain homeostasis.
- Homeostasis is maintaining a stable internal environment.
- Homeostasis often relies on negative feedback (e.g., regulating blood glucose levels).
- Behaviors & adaptations can support homeostasis.
- Examples of adaptations influencing homeostasis:
- Polar bear fur reflecting light for temperature regulation.
- Giraffe's long neck for accessing high-up vegetation.
- Giraffe's long eyelashes to keep dirt out of the eyes.
- Peacock's brightly colored tail for attracting mates.
- Cactus thorns for trapping air, gathering water, and providing shade.
- Examples of adaptations influencing homeostasis:
-
Evolution explains life's unity and diversity through changes over time.
- Genetic makeup of populations changes.
- Evolution proceeds through natural selection of beneficial inherited traits (adaptations).
-
Biology's discoveries improve human lives.
- Biological knowledge is applied to solve society's problems.
