    • Plant Tissues Biology Year 2
    • What are our objectives?
      • Classify
      • Identify, group and locate
      • Characterize
      • Give significant functions
    • Plant tissues
      • Two types of plant tissues
        • Meristematic
        • Permanent
    • Meristematic tissues
      • Responsible for production of new cells
      • Found in tips of growing stems and roots
        • Apical
        • Lateral
    •

    • Permanent tissue
      • Surface tissue
      • Fundamental tissue
      • Vascular tissue
    • Surface tissue
    • Fundamental tissue
      • Parenchyma
        • Thin-walled, no secondary walls
        • Contain most of chloroplasts
        • Store food and water
    • Fundamental tissue
      • Collenchyma
        • Similar to parenchyma
        • Elongated and irregularly thickened
        • Provides support
    • Fundamental tissue
      • Sclerenchyma
        • Derived from Greek, meaning “hard”
        • Dead cells with thick cell walls
        • Strengthen the plant body
    • Vascular tissue
      • Transport
        • Xylem
          • Water and mineral salts
        • Phloem
          • Food materials
    • H.W.
      • What is a vascular bundle? Identify the parts and function.
    • H.W.
      • What is a monocot? What is a dicot?
      • What arrangement of vascular bundles is found in monocots? In dicots?
