Translocation
- Sucrose is loaded into the sieve tube elements
- Water potential in the sieve tube is reduced
- Water moves into the sieve tube element from the xylem by osmosis
- Down a water potential gradient
- This causes the hydrostatic pressure to increase
- Energy in the form of ATP is needed for this
- That energy is used to remove H+ Ions
