  1. Transport in Plants

  2. Plants require: CO2 Light Sugar H2O O2 Minerals Macronutrients (besides C, H, O) Ca, K, Mg, N, P, S Micronutrients B, Cl, Cu, Fe, Mn, Mo, Ni, Zn

  3. Water goes up the Xylem From root To leaf then Transpires

  4. Sugar made In the leaf Goes down The Phloem

  5. How do roots absorb water and minerals?

  6. How does xylem transport xylem sap? Nearly all of the energy to drive the process comes from the sun Evaporation at the top pulls water up from the bottom Unbroken chains of water molecules fill xylem vessels

  7. How does xylem transport xylem sap? Water vapor escapes through stomata

  8. How does phloem transport phloem sap? Food (sugars) are then moved from leaves to the rest of the plant

  9. Not all herbivores chew leaves… Some exploit sap E.g., aphids tap sieve-tube elements for phloem sap

  10. Summary • Xylem is

  11. H/W • P97 • Q 3,5,7,8.
