4.
Trichromes
| 1. | Cilia | 2. | Trichomes |
| 3. | Trichoderms | 4. | Trichromes |
Trichomes help in
| 1. | Preventing water loss |
| 2. | Have sensory role |
| 3. | Help in combating grazing animals |
| 4. | None of the above |
All tissue except ____________ constitute the ground tissue.
| 1. | Epidermis |
| 2. | Vascular bundles |
| 3. | Both (1) and (2) |
| 4. | Cuticle |
In leaves the ground tissue consist of thin walled chloroplast containing cells and is called____.

The vascular system in plant consist of
| 1. | Xylem and phloem |
| 2. | Xylem parenchyma and cortex |
| 3. | Epidermis and cortex |
| 4. | None of the above |
In dicotyledonous stem _________ is present between phloem and xylem.
| 1. | Cork |
| 2. | Cambium |
| 3. | Connecting vessel |
| 4. | Connecting tubes |
The presence of cambium possess the ability to form secondary xylem and phloem tissue and hence are called
| 1. | Open vascular bundle |
| 2. | Closed vascular bundle |
| 3. | Intermediate vascular bundle |
| 4. | End node vascular bundle |
In monocotyledons the vascular bundle have no ________ present in them.
1. Xylem
2. Cambium
3. Cork
4. Phloem
Since there is no cambium present in monocotyledons they are referred to as
| 1. | Open vascular bundle |
| 2. | Closed vascular bundle |
| 3. | Intermediate vascular bundle |
| 4. | End node vascular bundle |
When xylem and phloem within a vascular bundle are arranged in an alternate manner on different radii such arrangement is called _______ and found mostly in __________.
(1) Radial, roots
(2) Radial, shoots
(3) Conjoint, roots
(4) Conjoint, shoots
