UNIT 7 Photosynthesis
Unit Outline
IB Roadmap: B2, B4, C1
Form & Function (B)
Adaptations are forms that correspond to function. These adaptations persist from generation to generation because they increase the chances of survival.
Interaction and Interdependence (C)
Systems are based on interactions, interdependence and integration of components. Systems result in the emergence of new properties at each level of biological organization.
