Physiology (Greek phýsis = nature and lógos = teaching) is the study of the fundamentals of life, in particular the life processes and functions in an organism. In detail, these are the biophysical life processes in the cells, tissues and organs of all living beings in the interaction of all physical, chemical and biochemical processes. Plant physiology is the study of the life processes of plants with the central life process of photosynthesis (picture). Other aspects are growth processes, differentiation of organs, reactions to environmental stimuli, transport of substances and communication between cells, tissues and organs. In the case of the vine, there is the concept of physiological maturity, which is important in the grape harvest. On the other hand, morphology (Greek morphé = shape, form) is the study of forms and characteristics and phenology (Greek phaíno = I appear) is the study of seasonal manifestations or the development cycle in organisms.
