Seed Plant Structure • What are the 3 principal organs of seed plants? • Roots • Stems • Leaves
Plant Tissue Systems • Dermal Tissue- protective outer covering of a plant. (epidermis) Brown=Dermal
Vascular Tissue • Supports & transports water & nutrients. • Includes Xylem (water) & Phloem (food) Vascular= Red/Yellow
Ground Tissue • Produces & stores sugars, & helps support Ground= grey Parenchyma, Collenchyma, Sclerenchyma
