Plant Physiology is the study of the functions and processes of plants. It encompasses various aspects such as photosynthesis, respiration, and nutrient uptake, which are essential for plant growth and development. Understanding these processes helps scientists and farmers improve crop yields and manage plant health effectively. Additionally, Plant Physiology explores how plants respond to environmental factors like light, temperature, and water availability. This knowledge is crucial for developing sustainable agricultural practices and conserving plant biodiversity. By studying plant hormones and signal transduction, researchers can uncover how plants adapt to changing conditions.
