Answer»
- Plant physiology is a basic discipline which intimately interfaces with biochemistry, agronomy, genetics and plant breeding, SOIL SCIENCE, plant pathology, microbiology and other related areas. Plant physiology explains various aspects of plant growth. It tells us how the constituent cells which MAY look alike individually, respond to a division of labour and perform organ-specific functions.
- Plant physiology also tells us how plants respond to the changing environments to which their cells are so freely exposed and control their behaviour in growth, senescence and REST.
- The gain in knowledge in this discipline has become really enormous. In the last few decades, several discoveries have been made which have revolutionized the basic CONCEPTS of plant physiology and have added to our knowledge of this subject.
- Many older hypotheses and assumptions are now invalidated, yielding place to new ideas. However, many important new discoveries are not entirely new but are additions to already existing concepts.
- The rapid expansion of knowledge about plant processes has resulted more from continuous improvements in experimental techniques and instruments than from recognition of new concepts.
