a.  Bryophytes

b.  Mosses

c.  Most gymnosperms

d.  Angiosperms

e.  Both a & b

f.  Both c & d

2.  Which of the following events may result from the clear-cutting of tropical forests?

a.  Rise in temperature and decrease in rainfall in the area

b.  Loss of potential medicines

c.  Increase in atmospheric CO2 levels

d.  Extinctions of many plant and animal species

e.  All of the above

3.  Which structure is incorrectly paired with its tissue system?

a.  Root hair – dermal tissue

b.  Palisade parenchyma--- ground tissue

c.  Guard cell --- dermal tissue

d.  Companion cell ---- ground tissue (should be phloem)

4.  Which of the following is an ongoing trend in the evolution of land plants?

a.  Decrease in the size of the leaf

b.  Reduction of the gametophyte phase of the life cycle

c.  Elimination of sperm cells or sperm nuclei

d.  Increasing reliance on water to bring sperm and egg together

e.  Replacement of roots by rhizoids

5.  Compare and contrast the 4 characteristics of monocots & dicots.

Monocots: 1 seed leaf/cotyledon, veins run parallel, fibrous/mesh-like roots, scattered vascular tissue

Dicots: 2 seed leaves/cotyledons, netlike veins, taproot, vascular tissue in rings

6.  Discuss the process by which fruit appears on an angiosperm, including the function of the pericarp.

Angiospermàovuleàseedàovary wall (which becomes pericarp)

Pericarps: protects and disperses the seeds

7.  What are the two types of vascular tissue and what are their components?

Xylem: Tracheids: transports water and minerals

Fiber cells: structural support

Vessel elements: water and mineral transport

Phloem: Sieve tube elements: move phloem sap from cell to cell

Companion cells: nuclei function for sieve tube elements and companion cells

8.  Draw the angiosperm life cycle. Indicate the ploidy of each step.

TEST TIPS:

Know the ins and outs of all the life cycles. If you need to, draw these out in detail several times to help you remember.

Vocabulary can get dense, so work on distinguishing terms. Make notecards to drill yourself!

Make sure you can compare and contrast the different life cycles and know the evolutionary trends.
