Roots, Stems, and Leaves Review Quiz:
1. Which of these do nonvascular plants LACK?
Root-like structures Stem-like structures Structures for water conduction Structures for photosynthesis
2. Is a stem with a “pepperoni pizza” distribution of scattered vascular bundles a monocot or dicot?
Monocot Dicot
3. When a stem has an orderly “birthday candle” distribution of vascular bundles is it a monocot or a dicot?
4. Which of these regions (divisions) is located directly above the root cap?
Region of maturation Region of elongation Region of cell division Region of cell structure
5. Which of these structures is responsible for keeping water inside the root?
Epidermis Pericycle Apical meristem Endodermis
6. What is the function of the apical meristem?
Food storage Photosynthesis Rapid growth Pigment storage
7. Does a monocot root have an x-shaped pattern of vascular tissue or a random distribution?
It has an x-shaped pattern It has a random distribution. Each monocot is different from all others. Only dicots have vascular tissue in their roots.
8. Which of these is responsible for air exchange within a leaf?
Guard cells The pericycle The cuticle Midribs
9. Which of these is responsible for transportation of nutrients?
Xylem Phloem Midribs Guard cells
10. Epidermal hairs help increase surface area for absorption. Which of these is their functional classification group?
Sieve cells Companion cells Trichomes Parenchyma cells
11. Sieve tubes (sieve elements) are associated with which of these tissues?
Parenchyma Xylem Stomata Phloem
12. Which of these tissues includes the companion cells?
13. What is the purpose of the root cap?
The root cap assists with absorption of water. The root cap is for surface protection. The root cap is the main area for cell division. The root cap provides a region for food storage.
14. Which of these is associated with the upper epidermis of a leaf?
Keratin Melanin Cutin Globin
15. Which of these is associated with guard cells?
Epidermal hairs Cuticle Midrib Stoma
