Plant cell organization

 

Organs:

  • Stems
  • Roots
  • Leaves

Tissues:

  • Epidermal
  • Meristem
  • Xylem and phloem
  • Palisade mesophyll
  • Spongy mesophyll

Leaves contain epidermal, mesophyll, xylem and phloem

Phloem: translocation

  • Made of columns of elongated cells with pores in the end walls to let cell sap flow. Transport food (dissolved sugars) made in leaves to rest of plant. transport goes in both directions

 

Xylem:

  • Made of dead cells joined end to end with no end wall. Strengthened with lining. Carry water and minerals from roots to stem and leaves.
