Soil–Plant Interactions and Nutrient Uptake Mechanisms Explained | Chapter 7 of Plant Physiology and Development Chapter 7 of Plant Physiology and Development explores how plants acquire essential mineral nutrients from the soil—a highly complex process shaped by soil chemistry, root architecture, membrane transport, and symbiotic partnerships. This chapter explains how nutrients become available in the soil, how roots locate and absorb them, and how the plant regulates uptake under varying environmental conditions. Understanding soil–plant nutrient interactions is central to plant physiology, ecology, and agriculture. For a clear overview of these key principles, watch the full Last Minute Lecture summary below. Watch the full chapter breakdown here: Soil Composition and Nutrient Availability Soil is a dynamic system composed of mineral particles, organic matter, water, and air. Several soil properties determine how available nutrients are to plants: Soil pH – influenc...

Essential Mineral Nutrients in Plants: Uptake, Transport, and Deficiency Symptoms | Chapter 6 of Plant Physiology and Development Chapter 6 of Plant Physiology and Development provides a comprehensive overview of the mineral nutrients required for plant growth and survival. These nutrients support every aspect of plant physiology—from enzyme activation and membrane stability to redox reactions, osmotic balance, and structural integrity. This chapter explains how essential nutrients are identified, how plants acquire them from the soil, how they move through vascular tissues, and how deficiencies manifest in plant tissues. For a clear and accessible walkthrough of these core ideas, watch the full Last Minute Lecture summary below. Watch the full chapter breakdown here: What Makes a Nutrient “Essential” to Plant Life? A mineral element is considered essential if: The plant cannot complete its life cycle without it. Its function cannot be substituted by another element. ...
