    1. IB Biology Review Chapter 36: Plant Transport

    2. What substances need to be transported throughout the plant? Water Sugars / energy / sap Nutrients Hormones

    3. How does water get into the plant? Through the roots Apoplastic route Symplastic route What adaptation do roots have to increase surface area? Root hairs Mycorrhizae fungus

    5. Apoplastic Route Water enters the route between cells Infiltrates around cells Hits Casparian strip (waxy buffer) Water is forced to be absorbed through a cell membrane Why should all water be forced through a cell membrane? Prevents contaminants from being absorbed into the plant

    6. Symplastic Route Water is absorbed through the cell membrane of a root hair cell Water travels through cells via connecting structure called a plasmodesmata

    7. Apoplastic and Symplastic Routes
