Q. No.Which of the following is a feature of the anatomy of a monocot stem?
I. Collenchymatous hypodermis
II. Scattered vascular bundles
| 1. | Only I | 2. | Only II |
| 3. | Both I and II | 4. | Neither I nor II |
In a monocot stem:
| 1. | Each vascular bundle is surrounded by a sclerenchymatous bundle sheath |
| 2. | Ground tissue is very poorly developed |
| 3. | Vascular bundles are conjoint and open with water containing cavities |
| 4. | Phloem parenchyma is present |
While looking at a T.S. of a certain plant part you are convinced that it must be a monocot stem. Which of the following, if seen in the T.S. will give you confidence for your conclusion?
| 1. | Conjoint vascular bundles |
| 2. | Presence of a hypodermis |
| 3. | Presence of phloem parenchyma |
| 4. | Presence of water containing cavities within the vascular bundles |
Identify the option where the difference between the vascular bundles of Dicot and Monocot stem is not correctly mentioned:
|
|
Dicot stem |
Monocot stem |
|
1. |
Collateral and open |
Collateral and closed |
|
2. |
Arranged in a ring |
Scattered |
|
3. |
Larger toward the center |
Of uniform size |
|
4. |
Phloem parenchyma present |
Phloem parenchyma absent |
Match the plants in Column I with the description of anatomy of vascular bundles in them in Column II and select the correct option from the codes given:
|
Column I |
Column II |
|
A. Dicot stem |
a. Collateral, closed and scattered in ground tissue |
|
B. Monocot stem |
b. Conjoint, collateral endarch and open |
|
C. Dicot root |
c. Radial, exarch and polyarch [usually more than 6] |
|
D. Monocot root |
d. Radial, exarch and 2 to 6 in number |
