Foundations of Transport in Plants

Understanding how plants move resources is key to grasping plant physiology and ecology. This fundamental biological process dictates survival, growth, and interaction with the environment. By the end of this course, you will have a comprehensive written understanding of the physical and physiological mechanisms that drive transport, from cellular uptake of water to the long-distance translocation of sugars. What you'll learn: * Understand the core concepts of diffusion, facilitated diffusion, and water potential across plant cell membranes. * Learn the mechanisms of water absorption, root pressure, and the crucial role of the transpiration pull in xylem transport. * Analyze the processes involved in mineral nutrient uptake, including active transport and ion exchange mechanisms in roots. * Master the pressure flow hypothesis to explain the translocation of organic solutes (sugars) through the phloem. * Practice applying concepts of water potential and membrane permeability to solve foundational biological problems. The course begins by defining fundamental transport principles at the cellular level before moving into detailed explanations of water and mineral uptake in roots, culminating in a thorough examination of long-distance transport through the vascular system (xylem and phloem). This course is designed for absolute beginners in biology or botany. No prior knowledge of plant anatomy or physiology is required.
