Water containing cavities in the vascular bundle is a characteristics feature of
| 1. | Dicot roots | 2. | Monocot stems |
| 3. | Monocot leaves | 4. | Dicot stems |
Monocot stems do not have
| 1. | Protophloem |
| 2. | Phloem parenchyma |
| 3. | Companion cell in phloem |
| 4. | Sieve tube and metaphloem |
The given transverse section is of:

| 1. | Monocot stem | 2. | Dicot stem |
| 3. | Monocot root |
4. | Dicot root |
The hypodermis of the monocot stem is made up of
| 1. | collenchyma | 2. | sclerenchyma |
| 3. | parenchyma | 4. | All of the above |
The diagram given below belongs to -
| 1. | Dicot stem having conjoint and collateral vascular bundles |
| 2. | Monocot stem having conjoint and collateral vascular bundles |
| 3. | Dicot root with polyarch condition |
| 4. | Monocot root with radial vascular bundles |
Which type of cells are not present in Phloem of monocot stem
| 1. | Companion cell | 2. | sieve tubes |
| 3. | Phloem parenchyma | 4. | Phloem fibres |
Vascular bundle are ___________and surrounded by ___________ bundle sheath in
monocot stem.
| 1. | scattered, sclerenchymatous |
| 2. | arranged, sclerenchymatous |
| 3. | scattered, parenchymatous |
| 4. | scattered, collenchymatous |
Conjoint, collateral, closed vascular bundles without phloem parenchyma are found in plants which have
| 1. | Differentiated ground tissue in the stem |
| 2. | Dedifferentiated pericyclic structure in the mature root |
| 3. | Sclerenchymatous hypodermis in stem |
| 4. | Developed pith in stem |
Consider the following statements:
In a monocot stem-
| I: | Hypodermis is collenchymatous. |
| II: | Vascular bundle are collateral and closed. |
| III: | Trichomes are usually absent. |
Which of the above statements are true?
| 1. | I and II only | 2. | I and III only |
| 3. | II and III only | 4. | I, II and III |
In monocotyledonous stem
| 1. | Hypodermis is parenchymatous |
| 2. | Each vascular bundle is surrounded by collenchymatous bundle sheath |
| 3. | Peripheral vascular bundles are generally larger than centrally located ones |
| 4. | Water containing cavities are present within the vascular bundles |
