[!ANSWER]

The scope of Botany with reference to Plant Physiology lies in translating an understanding of how plants function into practical improvements in cultivation.

Plant Physiology is the branch of Botany that studies the internal functioning of plants — processes such as photosynthesis (how plants manufacture food using sunlight), respiration (how plants release energy from that food), transpiration (the loss of water vapour through leaf pores), and the uptake of water and mineral nutrients from the soil through the roots. Understanding these processes in detail is not just of academic interest; it has direct practical value in cultivation. For example, stomata are the tiny pores on a leaf's surface through which a plant loses water vapour and exchanges gases with the atmosphere; understanding how stomata open and close under different conditions (such as light, humidity, and water availability) helps farmers and horticulturists plan irrigation schedules more efficiently — watering at the right time and in the right amount to reduce water stress on crops. Similarly, physiological understandi …
