Plant physiology is the study of plant functioning and its behavior, both internally and externally. It involves all plant metabolisms like growth, respiration, stress-tolerance, transpiration, seed germination, hormonal functions, seed dormancy, and plant interactions. Plant physiology is a broad area that involves the study of five major fields that are, plant cell biology, plant morphology, plant ecology, plant molecular biology, and plant biochemistry.
