Plant physiology is the study of how plants function, grow, and survive. This includes the study of plant metabolism, cell growth and division, water and nutrient uptake, photosynthesis, and responses to environmental stimuli. Plant physiologists use a range of scientific techniques to study plant physiology, including molecular biology, biochemistry, and microscopy. They work to understand the complex systems that allow plants to thrive in different environments and to identify ways to improve plant growth and productivity. It is a specialized skill that requires in-depth knowledge of plant biology and a variety of research methods.
