Plant Transport [IB Biology SL/HL]

In this video, we’ll explore the Key Concept of Transport in Plants, which allows them to grow as high as 100 meters. We will review transpiration, the structural adaptations of xylem vessels, and the distribution of tissues in a dicot stem and a root. For Higher Level content, we will review how root pressure contributes to water movement and how the phloem is adapted for translocation. Finally, we’ll review how sugars move through the phloem in a process called translocation. 0:00 - Transpiration 4:33 - Movement of water in xylem 5:52 - Adaptations of xylem 7:33 - Distribution of tissue in a dicot stem 9:13 - Distribution of tissues in a dicot root 11:05 - Generation of root pressure [HL] 12:39 - Symplast and apoplast pathways 14:16 - Translocation of sap due to a pressure gradient [HL] More IB Biology Videos & Exam Questions can be found at: Revision Village - IB Biology https://www.revisionvillage.com
