Identifying Leaf Structures in a Dicotyledonous Plant (Cambridge International IGCSE Science)

Identifying Leaf Structures in a Dicotyledonous Plant

• The leaves of dicotyledonous plants contain the following structures:

  • Chloroplasts
  • Cuticle
  • Guard cells
  • Stomata
  • Upper and lower epidermis
  • Palisade mesophyll
  • Spongy mesophyll
  • Air spaces
  • Vascular bundles containing xylem and phloem
