Section 3: Seed Plants Chapter 3 Page 88

Question 1 Answer List four characteristics common to all seed plants. Seed plants have roots, stems, leaves, vascular tissue, and produce seeds.

Question 2 Answer Compare and contrast the characteristics of gymnosperms and angiosperms. Gymnosperms produce seeds not protected by fruit; most have needlelike, evergreen leaves. Angiosperms produce flowers that become fruits that enclose seeds.

Question 3 Answer Classify a flower with five petals as a monocot or a dicot. It is from a dicot.

Question 4 Answer Explain why the root system might be the largest part of a plant. Roots must absorb large amounts of water and nutrients and anchor plants.

Question 5 Answer Think Critically: The cuticle and epidermis of leaves are transparent. If they weren’t, what might be the result? Less light would reach the chloroplasts, which would reduce the rate of photosynthesis.

Question 6 Answer Form a hypothesis about what substance or substances are produced in palisade cells but not in xylem cells. Hypothesis should include information that shows the connection between the presence of chloroplasts in cells and sugar production.
