Translocation which is the transportation of material e.g glucose which take place in the phloem cells have sievetube surrounded by sieveplates lisuid food moves down from production size of fertization through the sieve tubes and pores. Food usually moves downward from the leaves through the phloem tissues and to other part of the plants. While water and minerals salt move upward from the roots through the xylem tissues other parts. Glucose, amino acid, fatty and glycerol diffuses through one sieve tube to the other along the tugar pressure gradient from one leave to the storage organ.
