Key Concepts

Growth

This concept involves the increase in size, mass, or number in living organisms. It includes both an accumulation of biomass in individuals and an increase in numbers, especially evident in organisms that reproduce. Understanding growth is fundamental in biology as it involves cellular processes and the regulation of development across different life forms.

Metabolism

Metabolism encompasses all the chemical reactions that occur within living organisms to maintain life. It includes pathways that convert food into energy, as well as processes that synthesize necessary molecules. These reactions can be studied even outside the organism, using cell-free systems which isolate enzymes and substrates to demonstrate metabolic activity.

Response to Stimuli

This concept refers to the ability of living organisms to detect and react to changes in their environment. It is considered one of the defining characteristics of life, as it enables organisms to adapt to their surroundings, maintain homeostasis, and ensure survival in variable conditions.
