5 Matching questions

  1. Zone Of Cell Elongation
  2. Primary Tissues of Roots
  3. Zone Of Cell Division
  4. Stomata
  5. Cork Cambium
  1. a -Above the zone of cell division
    -Cells elongate to at least 10x their original length
    -Elongation of cells here pushes the root tip through soil
  2. b Pores flanked by guard cells which regulate gas exchange and allow for transpiration (water loss)
  3. c -Near tip of root
    -Includes apical meristem and quiescent center (slowly dividing cells may serve as replacement cells in the event of damage to meristem)
  4. d -Produces a tough, thick covering for roots and stems that replaces the epidermis
    -Form to the outside
  5. e -Protoderm
    -Ground Meristem

5 Multiple choice questions

  1. Thickening of roots and shoots
  2. -Outermost primary meristem
    -Gives rise to to epidermis
  3. -located between protoderm and procambium
    -Has endodermis (innermost layer of cortex; forms boundary between cortex and stele)
    -Stores food
    -FIlls the cortex (root area between stele and epidermis)
    -Gives rise to ground tissue system
  4. lower half of leaf cells equipped to perform photosynthesis
  5. -Vascular bundles scattered randomly (PIZZA)
    -Stem ground tissue is mostly parenchyma

5 True/False questions

  1. Primary GrowthThickening of roots and shoots


  2. DICOTS HAVE....-Ground tissue includes PITH (inside) and CORTEX (outside)
    -Vascular bundles are arranged in a RING with XYLEM facing PITH (inside)
    PHLOEM facing CORTEX (outside)


  3. Vascular Cambium-Produces a tough, thick covering for roots and stems that replaces the epidermis
    -Form to the outside


  4. Procambium-Forms a stele where xylem and phloem develop
    (difference between monocots and dicots!)


  5. Tissue Organization of Stems-Vacular tissue is organized into strands of vascular bundles that run the length of the stem
    -Each vascular bundle is surrounded by ground tissue
    -These converge at the shoot - root transition to join the root stele
