| a. | In roots, xylem and phloem in a vascular bundle are arranged in an alternate manner along the different radii. |
| b. | Conjoint closed vascular bundles do not possess cambium. |
| c. | In open vascular bundles, cambium is present in between xylem and phloem. |
| d. | The vascular bundles of dicotyledonous stem possess endarch protoxylem. |
| e. | In monocotyledonous root, usually there are more than six xylem bundles present. |
| 1. | (a), (c), (d) and (e) only | 2. | (a), (b) and (d) only |
| 3. | (b), (c), (d) and (e) only | 4. | all statements are correct |
| 1. | Dicot stem, due to early disintegration of protoxylem elements |
| 2. | Monocot stem, resulting from the breakdown of protoxylem during development |
| 3. | Dicot root, due to radial arrangement of vascular tissues |
| 4. | Monocot root, due to presence of large pith |
