Instructions: Look for representative specimens of herbaceous dicot and monocot stem. The external parts that can be observed are nodes, internodes, leaf scar, lenticel, and buds (axillary and terminal).
Examine and compare their external morphology by answering the questions below:
1. Why are terminal buds considered an active part of the stem?
2. Of what importance are nodes to the plant?
3. What are inter nodes and where are they located?
4. What is the function of the lenticels? Do all stems have lenticels?
5. How can you differentiate a monocot plant from a dicot plant just by looking at the stem?
6. What advantage would herbaceous stems have over woody stems?
7. What advantage would woody stems have over herbaceous stems?

Field Notes: Specimen collected from rocks on bank of streams from the Adirondack Park (NY). Plant growth form is more ‘prone’ than upright (plant seems to have little support).Laboratory Analysis:Body: Consists of three regions: light brown anchoring tissue (base of plant); Green vegetative area (middle of plant); Brownish-green, stalk-like structure bearing capsule at end (top of plant).Size: 8 cm in lengthChromosomal Analysis: Bottom two thirds of plant is haploid (chromosome # 10), while top third of plant is haploid (chromosome # 20).Lignin test: NegativeCuticle: PresentLeaves: Absent, though they do possess green photosynthetic structures. Contains chlorophyll a, b; B-carotenes; xanthophylls.Roots: Absent, though they do possess anchoring (possibly absorptive) structures.Stem: Absent, though they do possess axis—no xylem or phloem present.Notes: Top third of plant may be separate but dependent stage of life cycle; Capsule at end of plant contains haploid spores.Life History:…
