Vascular system.
<P>
   Roots  absorb  water and minerals from the soil, and transport them up
   as xylem sap.
<P>
   During  photosynthesis,  leaves  take in CO[2 and expel O[2] and H[2]O
   through stomata. ]
<P>
   The  loss  of  water from stomata creates a force called transpiration
   that pulls xylem sap upward.
<P>
   Sugars  produced  by  photosynthesis  are transported as phloem sap to
   other parts of the plant.
