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

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.

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

        
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

The conjuctive tissues lie between the

1. Xylem and phloem

2. Pericycle and Endodermis

3. Epidermis and endodermis

4. Epidermis and hypodermis

Hypodermis in dicot stem is composed of
1. Parenchyma

2. Collenchyma

3. Sclerenchyma

4. Both 1. and 3.

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

In the given diagram, which is not related with (A)
as indicated in the diagram?

1. Complimentary cells.
2. Involved in the exchange of gases.
3. Lens-shaped opening called lenticels.
4. Found in herbaceous trees.
