Download Nutrient Flow - Structure and Function of Plants - Lecture Notes and more Study notes Biology in PDF only on Docsity! Nutrient Flow 1. Flow of macronutrients. 2. Flow of water into the roots (symplast, apoplast, and transcellular) 3. Endodermis and Casparian Strip 4. Flow of nutrients with water via the symplast 5. Now that we know the basic routes for water movement, how does it get to the top of a plant? 6. Cohesion-Adhesion-Tension Theory 7. Overall flow a. Water lost from the leaves b. Tension, Cohesion, Adhesion pulls water up the xylem c. Water uptake from the roots 8. Sink-Source Dynamics in Phloem (flow from source to sink) – involves water transport! 9. Conclusions a. Water is the critical media for all nutrient travel in the plant! i. Tension, adhesion, cohesion b. Roots uptake most of the macronutrients in inorganic forms. c. Leaves and other photosynthesizing tissues build the organic molecules and distribute via the phloem. i. Source-sink relations Docsity.com
