1. Plant Anatomy Lab
Bio 113

2. Exercise 1: Plant Morphology
Examine living bean plant
Label Herbaceous Plant figure

3. Exercise 2: Plant Primary Growth and Development
Observe prepared slide of Coleus stem tip.

4. Exercise 3: Cell Structure of Primary Tissues…Lab Study A: Stems
Thin section exercise…Omit
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

5. Monocot or Dicot?
Which is Which?

6. Monocot
Dicot

7. Exercise 3: Cell Structure of Primary Tissues…Lab 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

8. Buttercup root cross section

9. Exercise 3: Cell Structure of Primary Tissues…Lab 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.

10. Lilac leaf cross section

12. Trichomes of the Nettle family

13. Exercise 4: Cell structure of Tissues Produced by Secondary Growth
Observe prepared slides of basswood (Tilia) stem

14. Additional
View photo examples of modified stems and leaves (tendrils, thorns, bulbs, rhizomes, tubers, succulents).
Review introductory material in the beginning of the lab exercise…a lot of important (you’ll see it again) terminology.
