The 'Key Ideas' in Biology represent the fundamental axioms that underpin the study of all living systems across GCSE and A-Level specifications. These unifying principles include the cellular basis of life, the role of genetic information in determining structure and function, the continuous transfer of energy and matter within organisms and ecosystems, and the mechanisms of evolution driving adaptation. Mastery of these concepts provides the necessary framework for understanding specific topics such as bioenergetics, homeostasis, and ecology.
