  1. 23.1 Specialized Tissues in Plants p664

  2. Seed Plant Structure • What are the 3 principal organs of seed plants? • Roots • Stems • Leaves

  3. Plant Tissue Systems • Dermal Tissue- protective outer covering of a plant. (epidermis) Brown=Dermal

  4. Vascular Tissue • Supports & transports water & nutrients. • Includes Xylem (water) & Phloem (food) Vascular= Red/Yellow

  5. Ground Tissue • Produces & stores sugars, & helps support Ground= grey Parenchyma, Collenchyma, Sclerenchyma

  6. Meristematic Tissue • Q: How do meristems differ from other plant tissue? • A: Meristems are regions of unspecialized cells in which mitosis produces new cells that are ready for differentiation. • Unspecialized cells responsible for continuing growth. (happy=growing). • Found on the tip of a stem or root.(apical)
