Document Summary

Apical meristems: tips of all roots, increase plant length. Vascular cambium: give rise to secondary xylem and phloem. Cork cambium: produce cork cells outer surface and palloderm on inner. Xylem: conduct water/minerals from root upward: tracheid: long/thin, pits in walls, for support, vessel elements: short/wide, large openings, pits, attached together. Phloem: transport organic material synthesizes by plant: sieve tube members: living, form conduction tube, companion cells: enlarge nucleus, adjacent sieve. Stems: monocot stem: exam cross section of corn stem, vascular bundles: scattered, compose both xylem/phloem surround by bundle sheath of fibers, dicot stem (2), herbaceous: vascular tissue occurs as ring of separate vascular bundles. Pith: vas bundle surround, central area ground tissue: woody: xylem makes bulk of stem.

a) support the stem structurally and are dead fibrous cells that have thick walls

Answer choices: Parenchyma Phloem Sclerenchyma Xylem

b) transport water and nutrients up from the roots

c) characterized by large vacuoles, which store nutrients and food.

d) transport sugar formed in the leaves by photosynthesis to the rest of the plant to be used as food.

3. Match the eudicot stem terms to their definitions.

a)surrounds and protects the vascular bundle	Answer choices: Parenchyma Collenchyma Pericycle Cambium Pith
b)center portion of the stem
c) located underneath the collenchyma
d) strengthen young stems and synthesize food
e) contains cells that divide to produce new xylem and phloem

4. Suppose you chop down a plant in the woods and bring it home to examine. You cut a cross section of the stem and you note that it has pith in the center. How would you classify this plant?

5. You encounter a shrubby-looking plant that you cannot tell if it has true wood or not. Upon cutting it open cross-sectionally, you note a layer of cork cambium. What does this tell you?

The water-transporting cells of xylem tissue are tracheids and vessel members?

How is the structure of tracheids similar to the structure of vessel members?

How is the structure of tracheids different from the structure of vessel members?

How is the structure of both tracheids and vessel members related to their ability to serve as efficient water-conduction cells?

Sieve tube members are the conducting cells of phloem, specialized for the transport of metabolites within a plant. In what way do sieve tube members differ from a "typical" plant cell?

How do these differences improve the ability of sieve tube members to serve as efficient metabolite-conducting cells?

What is a companion cell, and what is its function?

To what tissue system does each of the following belong - tracheids, vessel members, sieve tube members, and companion cells?

The epidermis is a primary dermal tissue and the periderm is a secondary dermal tissue. Describe the most common cell types found in each of these tissues.

Both the epidermis and the periderm need to perform the same basic functions. What are those functions?

How does the structure of the epidermis contribute to those functions?
