Life Processes

Meaning and Essential Life Processes Life processes are the vital activities that living organisms perform to maintain and sustain life. Only those processes that are essential for survival and maintenance of life are considered life processes. The four main life processes discussed are nutrition, respiration, transportation,...

What is the overall chemical equation for photosynthesis?

The overall equation for photosynthesis is $6CO₂ + 6H₂O \xrightarrow{\text{Light Energy, Chlorophyll}} C₆H₁₂O₆ + 6O₂$. This shows how plants convert carbon dioxide and water into glucose (food) and oxygen using light energy and chlorophyll.

Differentiate between breathing and respiration.

Breathing is a physical process of inhaling and exhaling air, occurring in the lungs, and does not directly produce energy. Respiration, conversely, is a chemical process occurring within cells where food (glucose) is broken down to release energy in the form of ATP (Adenosine Triphosphate).
