translocation Flashcards

Q

summarise the mechanism of translocation

A
  • sucrose produced in leaves is loaded into sieve tubes via active transport (therefore requires energy)
  • lowers water potential, causing water to move in from the xylem
  • assimilates move along the sieve tube towards areas of lower hydrostatic pressure (sink). sucrose diffuses into surrounding cells where it is needed
