Chapter 21 Plant Organization and Homeostasis Student: ___________________________________________________________________________ 1. If you were studying the structures in plants which are responsible for taking in carbon dioxide you would be studying A. the roots. B. the flowers. C. the stems. D. the fruits. E. the leaves. 2. Most plants have a body divided into two main parts which are A. the leaf system and the stem system. B. the shoot system and the root system. C. the stem system and the root system.

Based on this information, which of the following would he or she not be interested in studying? A. The axillary buds B. The petioles C. The roots D. The internodes E. The nodes 4. The portion of the plant located at the shoot tip is referred to as A. the terminal bud. B. the petiole. C. the node. D. the internode. E. the vascular tissue. 5. If you were studying the regions of the plant where leaves are attached to the stem you would be studying A. the internodes. B. the terminal buds. C. the leaf blades. D. the nodes. E. the vascular tissues. 6. This figure shows the organization of the plant body. What does "e" represent? A. A lateral branch root B. The node C. The internode D. An axillary bud E. The terminal bud 7. This figure shows the organization of the plant body. What does "b" represent? A. A lateral branch root B. The node C. The internode D. An axillary bud E. The terminal bud 8. This figure shows the organization of the plant body. What does "d" represent? A. A lateral branch root B. The node C. The internode D. An axillary bud E. The terminal bud 9. Which of the following is not a function of the stem in most plants? A. To support the leaves B. To produce carbohydrates C. To carry carbohydrates D. To carry water E. To support lateral branches 10. Which of the following is not a function of the root system in plants? A. To absorb water B. To anchor the plant C. To absorb minerals D. To store carbohydrates E. To absorb carbohydrates 11. A plant physiologist is studying the structures found on plants which increase the absorptive capacity of the roots. Based on this information you would conclude that he or she is studying which of the following structures? A. The root nodes B. The root internodes C. The root petioles D. The root hairs E. The axillary roots 12. A biologist is studying an unknown species of plant and observes the following characteristics: the root xylem and phloem are in a ring, the vascular bundles are scattered throughout the stem, and the leaf veins form a parallel pattern. Based on these observations, the biologist could safely conclude that the plant is A. a monocot. ... View Full Document
