How does water get into the roots? Osmosis, of course. For anyone who needs it, here's a review of Osmosis media type="youtube" key="aubZU0iWtgI" height="315" width="560"

Three Major Pathways of Transport: Apoplast- Symplast- Plasmodesmata- Transmembrane- Bulk Flow-

Basic Run-down:
Transport occurs by diffusion, active transport, and long-distance bulk flow
 * Solutes pass through transport proteins embedded in the phospholipid bilayer
 * Most important transport proteins are proton pumps, they use ATP to pump (H+) out of the cell
 * This creates H+ gradient
 * Root pressure pushes water up the xylem for a few feet in tall trees, transpiration pulls the water for the rest of the way
 * Cotransport is when a transport protein couples the diffusion of one solute with active transport of another
 * Coattail effect of cotransport is responsible for absorption of neutral solutes such as sugar sucrose
 * Diffusion and active transport are for short distance transport
 * Long distance transport occurs through bulk flow, movement of a fluid driven by pressure
 * Xylem sap, the water and dissolved minerals in the xylem, get transported by bulk flow to veins
 * Bulk flow is much faster than diffusion or active transport, uses negative pressure
 * Water flows in from the root cortex generating root pressure, a push of xylem sap
 * Root pressure sometimes causes more water to enter the leaves than is transpired resulting in guttation
