5 Matching questions

  1. Zone Of Cell Elongation
  2. Procambium
  3. Apical Meristems
  4. Cork Cambium
  5. Stele
  1. a Located in root tips and shoot buds; involved in primary growth
  2. b -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
  3. c Central Cylinder
  4. d -Forms a stele where xylem and phloem develop
    (difference between monocots and dicots!)
  5. e -Produces a tough, thick covering for roots and stems that replaces the epidermis
    -Form to the outside

5 Multiple choice questions

  1. -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)
  2. -Produced secondary xylem and phloem
    -Xylem forms inside (wood)
    Phloem forms outside
  3. May sprout from the outermost layer of the stele (the PERICYCLE) - as a result, the lateral root maintains its vascular connection to the stele of the main root
  4. -Ground tissue includes PITH (inside) and CORTEX (outside)
    -Vascular bundles are arranged in a RING with XYLEM facing PITH (inside)
    PHLOEM facing CORTEX (outside)
  5. -Located farthest from the root tip
    -Where new cells become specialized

5 True/False questions

  1. Secondary Growth-The root tip contains 3 zones of cells
    -Near tip of rot
    -The root is covered by root cap which protects meristem and secretes a polysaccharide coating that lubricates the soil ahead of the growing root
    -Elongation

          

  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. ProtodermThe combination of cork cambium and layers of cork (xylem)

          

  4. Spongy ParenchymaUpper half of leaf; cellsare collum-shaped

          

  5. Primary Growth-The root tip contains 3 zones of cells
    -Near tip of rot
    -The root is covered by root cap which protects meristem and secretes a polysaccharide coating that lubricates the soil ahead of the growing root
    -Elongation
