Dicot Stem

In barley stem, vascular bundles are:

1. open and scattered

2. closed and scattered

3. open and in a ring

4. closed and radial

Read the different components from I to IV in the list given below and tell the correct order of the components with reference to their arrangement from the outer side to the inner side in a woody dicot stem.

I.	Secondary Cortex
II.	Wood
III.	Secondary phloem
IV.	Phellem

The correct order is:

1.	III, IV, II, I	2.	I, II, IV, III
3.	IV, I, III, II	4.	IV, III, I, II

Secondary xylem and phloem in dicot stem are produced by?

1.	Apical meristems	2.	Vascular cambium
3.	Phellogen	4.	Axillary meristems

Select the correct pair.

1.	Cells of medullary rays that form part of a cambial ring - Interfascicular cambium
2.	Loose parenchyma cells rupture the epidermis and form a lens-shaped opening in the bark - Spongy parenchyma
3.	Large colorless empty cells in the epidermis of grass leaves - Subsidiary cells
4.	In dicot leaves, vascular bundles are surrounded by large thick-walled cells - Conjunctive tissue

Give below are two statements :

Statement I:	Endarch and exarch are the terms often used for describing the position of secondary xylem in the plant body.
Statement II:	Exarch condition is the most common feature of the root system.

In the light of the above statements, choose the correct answer from the options given below:
1. Statement I is incorrect but Statement II is correct.
2. Both Statement I and Statement II are correct.
3. Both Statement I and Statement II are incorrect.
4. Statement I is correct but Statement II is incorrect.
