Using everyday plant scenarios, it links leaf air spaces, stomata, lenticels, and roots to efficient gas movement. It also highlights diffusion gradients and adaptations such as pneumatophores and aerenchyma that allow respiration in water-logged habitats.

It explains how light energy is stored as chemical energy in chloroplasts and later released in mitochondria to power cellular activities. Using day–night and environmental scenarios, it highlights how gas exchange, energy flow, and chemical pathways stay balanced in living plant cells. Khan Academy exercise
