4.2 Organisation¶
This topic area scales biology up from cells to whole organisms. It covers how tissues and organs work together, with enzymes, circulation and plant transport as the main examples.
Core Role¶
- Show how structure and function connect across tissues, organs and organ systems.
- Link digestion, blood transport and plant transport into one organised view of the body.
- Reinforce that effective biological systems depend on specialised parts working together.
