In dicot stem the vascular bundle is:-
| 1. | Conjoint, open and with exarch protoxylem. |
| 2. | Conjoint, open and with endarch protoxylem. |
| 3. | Conjoint and closed. |
| 4. | Scattered, each surrounded by a sclerenchymatous bundle sheath. |
The vascular bundle shown in the diagram is most likely to be seen in:
| 1. | Monocot stem | 2. | Dicot stem |
| 3. | Monocot root | 4. | Dicot root |
Vascular bundles in monocotyledons are considered closed because
| 1. | a bundle sheath surrounds each bundle |
| 2. | cambium is absent |
| 3. | there are no vessels with performations |
| 4. | xylem is surrounded all around by phloem |
Why are vascular bundles closed in monocots?
| 1. | Xylem and Phloem are present |
| 2. | Xylem and phloem occur in separate bundles |
| 3. | Vascular cambium is present between xylem and phloem |
| 4. | Vascular cambium is not present |
Vascular tissue system consists of
| 1. | xylem and Phloem |
| 2. | Phloem and cambium |
| 3. | Xylem, Phloem and cambium |
| 4. | All of the above |
In Dicots, Secondary growth is possible because of
| 1. | cambium |
| 2. | xylem and Phloem |
| 3. | Vascular bundle |
| 4. | Both 2. and 3. |
Radial vascular bundle arrangement is most common in
1. roots
2. stem, and roots
3. leaves
4. All of the above
In radial vascular bundle xylem and phloem are present on _____________radii and in an ___________manner.
| 1. | different and consecutive |
| 2. | same and alternate |
| 3. | different and alternate |
| 4. | same and consecutive |
In conjoint type vascular bundle xylem and phloem are present on _________ radii and & phloem is located on the __________side of the xylem.
1. same and outer
2. same and inner
3. different and inner
4. different and outer
