Primary tissues arise: during secondary growth 4. Cells which are typically in xylem but not a. in other plant tissues are: tracheids from the three primary a. b. meristematic tissues vessel elements b. from the vascular cambium c. both tracheids and vessel elements c. from the cork cambium d. neither tracheids nor vessel elements d. from two of the above e. companion cells e. 2. Secondary growth: occurs in all angiosperms a. 5. The secondary cell walls of adjacent cells: lie in direct contact with one another a. is accomplished by the procambium b. are separated from one another by b. the middle lamella is accomplished, at least c. in part, by the vascular cambium are separated from one another by the c. primary walls and the middle lamella brings about an increase in d. the height of the plant are formed following the death of the cells d. results in the formation of the e. endodermis play no significant role in cell function e. 3. The tissue most likely to provide flexible support is the: epidermis a. b. c. d. e. 6. Mature sieve-tube members lack: cell walls a. sclerenchyma b. parenchyma cell c. collenchyma d. cambium e. cell membranes cytoplasm nuclei sieve plates 7. The increase in diameter of the trunk of a tree is produced primarily by the: apical meristem a. b. c. d. e. cork cambium b. pith c. vascular cambium d. cork e. 8. In a three-year-old stem, the oldest secondary xylem is found: adjacent to the pith a. b. c. 10. The tissue formed on the outside of a woody stem is called: bark a. b. just outside the vascular cambium c. immediately adjacent to the d. primary phloem d. immediately adjacent to the e. secondary phloem e. the most abundant tissue would b. be the secondary phloem secondary xylem and secondary c. phloem would be equally abundant the most abundant tissue would d. be the cork secondary phloem endodermis are epidermal cells arise from the endodermis function in support two of the above 12. The apical meristem in the root: is located behind the root cap a. produces cells which become b. incorporated into the root cap gives rise to the primary c. meristematic tissues d. e. the oldest vascular cambium e. would be inactive cortex 11. Root hairs: are multicellular filaments a. just inside the vascular cambium 9. In a twenty-year-old woody stem: the most abundant tissue would a. be the secondary xylem cork is a region of active cell division all of the above 16. Draw and explain the major differences between the structures of Monocot and Dicot Stems and roots below: 13. In a young root, the sequence of tissues from the outside to the center is: epidermis, pericycle, cortex, endodermis, a. primary phloem, primary xylem epidermis, cortex, endodermis, pericycle, b. primary phloem, primary xylem epidermis, cortex, primary phloem, c. primary xylem, endodermis, pericycle epidermis, primary phloem, cortex, d. primary xylem, endodermis, pericycle epidermis, cortex, pericycle, endodermis, e. primary phloem, primary xylem 17. Draw and explain the 3 main types of plant tissue and their component tissues. 14. In the root, the pericycle: is a single layer of cells just inside a. the epidermis b. c. arises from the ground meristem arises from the procambium is situated between the primary xylem d. and primary phloem regulates the movement of materials e. into the vascular tissue 15. The structure in the leaf that regulates water loss and gas exchange is the: cuticle a. b. c. d. e. epidermis palisade mesophyll spongy mesophyll stoma 18. Draw and explain the structure of a woody stem, be sure to explain the secondary growth.
