Plant TISSUES

• Dermal
  • epidermis (“skin” of plant)
  • single layer of tightly packed cells that covers & protects plant
• Ground
  • bulk of plant tissue
  • photosynthetic mesophyll, storage
• Vascular
  • transport system in shoots & roots
  • xylem & phloem

Parenchyma

 Parenchyma cells are unspecialized, thin, flexible & carry out many metabolic functions  all other cell types in plants develop from parenchyma
