Biology Question 95 – NEET-UG 2025
🧠 Full Solution Path
Reductionist Biology is an approach that seeks to understand complex biological systems by analyzing their constituent parts and processes at a more fundamental level. This often involves explaining biological phenomena in terms of underlying physical and chemical laws and mechanisms.
Option (1) 'Physico-chemical approach to study and understand living organisms' directly aligns with the definition of reductionism, as it focuses on the fundamental physical and chemical basis of life. Option (2) 'Physiological approach' studies functions at organ/system levels, which is less purely reductionist. Option (3) 'Chemical approach' is a part of the physico-chemical approach but less comprehensive. Option (4) 'Behavioural approach' focuses on higher-level interactions and is not reductionist in this context.
The term 'physico-chemical' encompasses both physical and chemical aspects, making it the most complete description of the reductionist view among the choices.
Based on the definition, the physico-chemical approach is the most accurate description of Reductionist Biology, as it involves breaking down biological complexity into its fundamental physical and chemical components.
