JEFF MACHEN -BIO 104 VASCULAR PLANT STRUCTURE
1. You should know all differences between Monocots and Dicots that we discussed
including what a cotyledon is. 2. You should be able to distinguish between the following types of plant tissues as
vascular tissues, parenchyma,
collenchyma, sclerenchyma,
xylem, and phloem. 3. You should know the characteristics of the following components of xylem and
phloem:
Vessel members, Tracheids, and
Seive-Tube members. 4. You should know the function and location of the following epidermal structures:
Trichomes, Stomata, Cuticle layer, Root hairs. 5. You should be able to distinguish between: apical and lateral meristems, primary
and secondary growth, positive phototropism and
positive geotropism. 6. You should be able to identify the following structures within a stem as to their description and function: pith, annual growth rings, secondary xylem, vascular cambium, secondary phloem, cork cambium, and periderm. Know
the stem modifications on page 747. 7. You should be able to identify the following structures associated with the root of a plant as to their description and function: epidermis, primary root, lateral root, root cap, cortex, casparian strip, pericycle. You should be able to visually recognize all structures on figure 35.3 and 35.15. ( including the zones of cell div., elongation, and maturation. Know the basic functions of the root, what an adventitious root is, and the root modifications on page 743. and function: cuticle, epidermis, stomata ( and guard cells), veins, palisade and spongy mesophylls, and trichomes. Be able to visually identify all leaf components from figure 35.34. Know the three basic types of leaf arrangement, what the petiole and axillary bud are, and the difference between simple and compound leaves. Know the leaf modifications on page 751. and recognize these structures from their descriptions: Example: The node is the site of attachment for a structure growing off of the stem of a plant.
