Importantce of Crop Physiology In Agriculture and Plant Cell Organelles
Crop physiology is concerned with the processes and functions of the crops at cellular,
sub-cellular and whole plant levels in response to environmental variables and growth.
However, In short, “plant physiology is the study of functional aspects of crop plants”.
Processes mean natural containing sequence of events. Photosynthesis, Respiration, Ion
absorption, Translocation, Transpiration, Stomatal opening and closing, Assimilation,
Flowering, Seed formation and Seed germination are examples of processes that occur in
living plants. Function means natural activity of a cell or tissue, or organ or chemical
substances. It describes and explains the function of an organ, tissue, cell and cell
organelle in plants. Both processes and functions are dependent on the external factors
and are modified by the external factors such as water, salt, light, temperature and
pollutions. It describes and explains how processes and functions respond to change in
the environment. The overall goal of plant physiology is to understand the natural of plant
growth, development and productivity.
