3. Which of the following is a major difference between vascular and nonvascular plants? A. Nonvascular plants must absorb water directly through their surfaces. B. Vascular plants only reproduce by producing seeds. C. Nonvascular plants produce fruit. D. Vascular plants can carry out photosynthesis in any of their tissues.
A. Nonvascular plants must absorb water directly through their surfaces.

4. Which answer best describes what happens in the meristem regions of plants? A. These regions, where cells continuously divide, are where plant growth originates. B. These regions, where the plant mines for water, are where starches are stored. C. These regions, where the plant gathers sunlight, are where photosynthesis takes place. D. These regions, where micronutrients are gathered, are where chemical conversion takes place.
A. These regions, where cells continuously divide, are where plant growth originates.

5. Which environmental habitat is most suitable for seedless nonvascular plants? A. dry desert terrestrial biome B. region with extreme fluctuations in temperature C. very cold area with limited herbivores D. damp area where nutrients can be directly absorbed
D. damp area where nutrients can be directly absorbed

6. Which of the following is true of angiosperms. A
Which of the following is true of angiosperms? A. They only grow in the tropical rain forest biome. B. They are all seedless plants. C. They have the same number of chromosomes. D. They have embryos enclosed in a fruit.
D. They have embryos enclosed in a fruit.

7. Which of the following are two adaptations that allow plants to preserve the moisture in their leaves while simultaneously allowing gas exchange for photosynthesis? A. vascular system and cotyledon B. guard cells and stomata C. xylem and phloem D. angiosperm and gymnosperm
B. guard cells and stomata

8. Which of the following are two reproductive structures that are unique to angiosperms? A. flowers and fruits B. seeds and cones C. cambium and stomata D. xylem and phloem
A. flowers and fruits

9. Which of the following specific plant cells function in providing support and are dead at maturity? A. parenchyma cells B. collenchyma cells C. sclerenchyma cells D. guard cells
C. sclerenchyma cells

10. Terrestrial plants have stomata on the surface of their leaves
Terrestrial plants have stomata on the surface of their leaves. A single stoma is surrounded by two guard cells that change shape in response to environmental factors and open or close the stoma. Which of the following best explains how the structure of the leaf is used in processes that occur in the plant? A. Water enters the plant through the surface of the leaf for transpiration. B. Gases for photosynthesis are exchanged through the surface of the leaf. C. Energy for cellular reproduction is absorbed through the surface of the leaf. D. Carbon dioxide enters the plant through the surface of the leaf for cellular respiration.
B. Gases for photosynthesis are exchanged through the surface of the leaf.

11. As plants grow, stems and branches thicken or increase in girth
As plants grow, stems and branches thicken or increase in girth. This thickening is a result of cell division in the vascular cambium. Vascular cambium can develop into either xylem or phloem tissue within a plant. Because of this unique ability, which of the following would NOT be a characteristic of vascular cambium cells?
a.  woody, re-inforced cell walls
b.  relatively undifferentiated
c.  able to undergo cellular
division
d.  simple, typical plant cells
woody, re-inforced cell walls
Oak tree cross section
