Exercise 3 Cell Structure of Primary TissuesLab
Study A Stems

• Thin section exerciseOmit
• Observe prepared slide of Dicot stem
  cross-section (Triarch slides are the best)
• Observe prepared slide of Monocot stem
  cross-section
• View poster
• View monocot and dicot stem demo

Exercise 3 Cell Structure of Primary TissuesLab
Study B Roots

• Observe prepared slide of buttercup (Ranunculus)
  mature root
• Observe prepared slide of Root hairs. (The root
  hair slide is a thick mount do not use high
  power objective to view this slide)
• View Root noodles demo
• View poster

Exercise 3 Cell Structure of Primary TissuesLab
Study C Leaves

• Observe prepared slide of Leaf cross section
  (lilac leaf)
• View Leaf model as reference on leaf cells
• Observe prepared slide of Stinging nettle
  trichomes.
• Trichomes (modified epidermal cells) that
  function in defense. Each trichome consists of a
  bulb filled with formic acid. The trichome
  injects the chemical irritant into the skin of an
  animal that touches the plant.

Exercise 4 Cell structure of Tissues Produced by
Secondary Growth

• Observe prepared slides of basswood (Tilia) stem

Additional

• View photo examples of modified stems and leaves
  (tendrils, thorns, bulbs, rhizomes, tubers,
  succulents).
• Review introductory material in the beginning of
  the lab exercisea lot of important (youll see
  it again) terminology.
