Interfascicular cambium in a dicot stem is formed from
1. Pericycle cells
2. Cortex cells
3. Medullary ray cells
4. Conjuctive parenchyma

In the dicot root, the vascular cambium originates from:

Tracheids are  
1. Elongated cells with tapering ends and unperforated end walls
2. Elongated cells with tapering ends and perforated end wall
3. Rounded cells with lignified walls
4. Both 1 and 2

The cells which give rise to a part of vascular cambium
in main root and laterals roots are

1. Parenchymatous cells of pericycle.
2. Collenchymatus cells of endodermis.
3. Parenchymatous cells of endodermis.
4. Meristematic cells of cortex.

Which of the following function can be performed by
both parenchyma and collenchyma?
1. Storage.
2. Photosynthesis.
3. Secretion.
4. All.

        
Which of the following matching is correct?

1. A – II, IV, VII, VIII; B – I, III, V, VI
2. A – I, II, VIII, VIII; B – III, IV, V, VI
3. A – I, III, V, VI; B – II, IV, VII, VIII
4. A – I, III, VII, VIII; B – II, IV, V, VI

Bark refers to all the tissues

1. External to vascular cambium

2. External to cork cambium

3. Formed earlier in the season

4. Impregnated with suberin

The conjuctive tissues lie between the

1. Xylem and phloem

2. Pericycle and Endodermis

3. Epidermis and endodermis

4. Epidermis and hypodermis

Lignin is a component of the secondary walls of:-

1. Epidermis

2. Collenchyma

3. Sclerenchyma

4. Parenchyma

Hypodermis in dicot stem is composed of
1. Parenchyma

2. Collenchyma

3. Sclerenchyma

4. Both 1. and 3.
