Detailed explanation-1: -Plant physiology is a branch of study in Botany dealing with the physiological processes or functions of plants. Precisely, it is a descriptive study of variation and structure of plants at the molecular and cellular level, resulting in ecological, physiological and biochemistry related aspects of plant exploration.

Detailed explanation-2: -Phytomorphology is the study of the physical form and external structure of plants. This is usually considered distinct from plant anatomy, which is the study of the internal structure of plants, especially at the microscopic level. Plant morphology is useful in the visual identification of plants.

Detailed explanation-3: -Plant Physiology is important to understanding the effects of environmental change on local and large-scale ecological health. As environments change the plants that have grown there for many years are often replaced by others that now grow better.
