Xylem Phloem Materials Plant End Transports Flow Cell

Both xylem and phloem transport materials in long hollow structures; xylem is largely non-living tissue for water and minerals from roots to shoots, while phloem is living tissue for organic solutes in both directions.

Tanto el xilema como el floema transportan materiales en estructuras huecas largas; el xilema es principalmente tejido no vivo para agua y minerales de raíces a brotes, mientras que el floema es tejido vivo para solutos orgánicos en ambas direcciones.

Front Compare structure & function of xylem and phloem.
Back Similarities:
  • Both transport materials around plant
  • Both made up of cells joined end to end forming long hollow structures

Differences:
  • Xylem largely non-living tissue, phloem living
  • Xylem transports water & mineral ions, phloem transports organic solutes around plant
  • Xylem flow of materials from roots to shoots and leaves, phloem flow of material up and down
  • Xylem cell walls lignified, phloem cell walls not
