23.1 Specialized Tissues in Plants

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

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)
