Xylem & Phloem

  • The xylem and phloem make up the transport system of vascular plants
  • The role of the xylem is to transport water and mineral ions from the roots to other parts of the plant
  • The role of the phloem is to transport sucrose and amino acids from where they are produced or stored, to where they are needed
    • E.g. sucrose and amino acids are produced in the leaves while plants photosynthesise, so they are transported from the leaves to other parts of the plant
