CertifiedPlant Physiology
This course provides an in depth exploration of the functional processes that enable plants to grow develop and respond to their environment Students will examine the fundamental physiological mechanisms that govern plant life including water relations mineral nutrition photosynthesis respiration and plant growth regulators The course emphasizes understanding how these processes are integrated to support plant survival and productivity
The course begins with plant water relations studying the absorption of water and minerals from soil Students will learn about the pathways of water movement through plants including the apoplast and symplast routes The mechanism of transpiration and its role in creating transpiration pull is examined in detail along with factors affecting stomatal movement The concept of water potential and its components solute potential and pressure potential are explored through practical problems
Mineral nutrition covers essential macro and micronutrients their functions deficiency symptoms and uptake mechanisms Students will study soil plant relationships and the role of microbes in nutrient cycling Special attention is given to nitrogen fixation both symbiotic and non symbiotic and the metabolism of nitrogen in plants
Photosynthesis is examined through its two main phases the light dependent reactions and the light independent Calvin cycle Students learn about photosynthetic pigments reaction centers electron transport systems photophosphorylation and carbon fixation pathways Factors affecting photosynthesis including light intensity carbon dioxide concentration and temperature are analyzed through experimental data
Plant respiration is studied through glycolysis the Krebs cycle and the electron transport system The course compares aerobic and anaerobic respiration and examines respiratory quotients for different substrates Alternative pathways in respiration are discussed along with their physiological significance
Plant growth and development covers the phases of growth measurement techniques and the role of plant growth regulators auxins gibberellins cytokinins ethylene and abscisic acid Students learn about photoperiodism vernalization and seed dormancy mechanisms The concept of phytochromes and their role in light mediated responses is explored in detail
Stress physiology examines how plants respond to environmental challenges including water stress salt stress and temperature stress Students learn about protective mechanisms and adaptations that enable plant survival under adverse conditions
The teaching approach combines theoretical knowledge with practical applications using experimental data and case studies Regular assessments include data interpretation questions and problem solving exercises based on physiological processes By course completion students understand how plants function at the physiological level and can apply this knowledge to agricultural practices and environmental management This foundation prepares students for advanced studies in botany agriculture and environmental science
