Vascular bundles are continuous from the root to the stem, but different arrangements are found in two cases. What would be true for this arrangement?
| 1. | In the stem they are collateral with endarch xylem while in the root they are radial with exarch xylem |
| 2. | In the stem they are collateral with exarch xylem while in the root they are radial with endarch xylem |
| 3. | In the stem they are radial with endarch xylem while in the root they are collateral with exarch xylem |
| 4. | In the stem they are radial with exarch xylem while in the root they are collateral with endarch xylem |

| 3. | 2 rings of xylem and 3 of phloem. |
| 4. | 3 rings of xylem and 1 of phloem. |
