Intro Bio 152 Lecture 2 Discussion Worksheet; week of 2/1/10 Draw, model or demonstrate how water is transported from the soil to the xylem. Draw, model or demonstrate the transport of K + ions from the soil to the xylem. Draw, model sugar transport TERMS: endodermis Casparian strip plasmodesmata stele channels root hairs ADP symplastic transport ATP apoplastic transport epidermis symplast lateral transport apoplast absorption xylem phloem ψ raffinose sugar sink sugar source Once you have finished working through xylem and phloem conduction, answer the following questions : 1. How do water’s properties of adhesion and cohesion help maintain the flow of water in the xylem of a plant? 2. If water flows from a region of more positive (higher) water potential to a region of more negative (lower) water potential, how does the water potential in the root compare to that in the soil outside the root? 3.
