2. Vascular plant tissue includes all of the • following EXCEPT • meristem. • sieve tube cells. • vessels. • tracheids. • companion cells. Answer: a

3. Which is CORRECT about monocots? • Vascular bundles in the stem are in a ring. • Their floral parts are usually in 3’s. • They usually have taproots. • The veins in the leaves are netlike. • All of the above. Answer: b

4. Cortex, mesophyll, epidermal cells, and pith • all consist of • parenchyma. • collenchyma. • schlerenchyma. • both b and c • all of the above Answer: a

5. To observe the process of mitosis in plant • roots, a student should examine the root’s • root cap. • zone of maturation. • meristem tissue. • pericycle. • endodermis. Answer: c

6. Which of the following tissue types gives rise to all other plant tissues? a. parenchyma b. collenchyma c. schlerenchyma d. xylem e. phloem Answer: a

7. stem root internode node petiole leaf blade Asexual (vegetative) organs

8. flower seed fruit Sexual Organs

9. root hairs guard cells Epidermal Tissue cork glands

10. parenchyma collenchyma Least specialized Ground Tissue (Filler) sclerenchyma

11. Vascular Tissue (Stele)

12. Plants constantly grow in specialized areas only! Meristem (embryonic tissue)

13. Embryonic root cross section

14. ground meristem (ground tissue) protoderm (epidermis) procambium (vascular tissue)

16. taproot (dicot) First root grows straight down ex. Beet fibrous root (monocot) Anchor/ hold soil ex. grss Secondary growth adventitious root pericycle Dicots- from vascular tissue Grow from lower nodes of stem

17. parasitic mutualistic haustoria mycorrhizae (fungus)

18. Soybean root nodules, each containing billions of Bradyrhizobium bacteria

19. Terminal bud Produces new cells that elongate, increasing length Continually differentiating Primary growth Mature non-woody stems (herbaceous) Most monocots Shoot Apical Meristem

20. rhizome stolon tuber tendril corm

21. (Stipules)

26. spines tendril Modified leaves bulb insect catching

27. Secondary growth Woody Stems Second and subsequent years Lateral meristem

29. Spring wood: wide vessels for transport Summer wood: more fiber and tracheids (less vessels) Spring wood + summer wood = annual ring

30. Cork Cambium Cork Wood Bark
