What is the number of correct statements amongst the following regarding the phloem tissue of plants?

I:	Gymnosperms lack albuminous cells and sieve cells.
II:	The companion cells are specialized parenchymatous cells.
III:	Phloem parenchyma is absent in most of the monocotyledons.
IV:	Phloem fibers are generally absent in the primary phloem.

1. 0

2. 2

3. 3

4. 4

In dicot roots, the initiation of the lateral roots and the vascular cambium during the secondary growth takes place in:

1. Pericycle

2. Endodermis

3. Conjuctive tissue

4. Epidermis

In dicot stem the vascular bundle is:-
1. Conjoint, open and with exarch protoxylem.
2. Conjoint, open and with endarch protoxylem.
3. Conjoint and closed.
4. Scattered, each surrounded by a sclerenchymatous bundle sheath.

Bulliform cells:

1. Are found in dorsiventral leaves and help in photosynthesis.

2. Are found in dorsiventral leaves and help in minimizing water loss.

3. Are found in isobilatetral leaves and help in minimizing water loss.

4. Are found in isobilatetral leaves and help in photosynthesis.

The endodermis is absent or indistinct in the:-
1. Roots of all plants
2. Leaves of pteridophytes
3. Leaves of gymnosperms
4. Stems of woody plants

The term 'bark' includes: 

I.      Phellogen

II.     Phellem

III.    Phelloderm

IV.     Secondary phloem

1.       I, II and III only

2.       I, II and IV only

3.       II, III and IV only

4.       I, II, III and IV only

Identify the incorrect statement:

1.  The presence of vessels is a characteristic of angiosperms

2.  In roots the primary xylem is exarch

3.  Gymnosperms lack albuminous cells and sieve cells

4.  Bast fibers are generally absent in primary phloem

The given transverse section is of:

1. Monocot stem

2. Dicot stem

3. Monocot root

4. Dicot root

The vascular bundle shown in the diagram is most likely to be seen in:

1. Monocot stem

2. Dicot stem

3. Monocot root

4. Dicot root

The main function of the plant tissue shown below is:

1. Storage of nutrients
2. Providing buoyancy to submerged plants
3. Mechanical support to growing parts of a plant
4. Increase in the length of the plant
