Read the following characteristics (I - IV) and identify the structure to which these features correspond
I. Cortex is made up of several layers of thin walled parenchyma cells without any intercellular spaces.
II Endoderm is made up of a single layer of barrel - shaped cells without any intercellular spaces.
III . Few layers of thick - walled parenachymatous cell forms pericycle.
IV. Pith is small or inconspicuous.
V. Conjunctive tissue present , and 2 to 4 xylem and phloem patches.

Options

A. Dicot root
B. Dicot stem
C. Monocot root
D. Monocot stem

Answer

To identify the structure corresponding to the given characteristics, we can analyze each point step by step:

### Step-by-Step Solution:

1. **Cortex Composition**:
- The cortex is described as being made up of several layers of thin-walled parenchyma cells without any intercellular spaces.
- This feature is typical of the root structure in plants, particularly in dicots where the cortex is prominent and composed of parenchyma.

2. **Endoderm Structure**:
- The endoderm is noted to be a single layer of barrel-shaped cells without intercellular spaces.
- This characteristic is consistent with dicot roots, where the endodermis serves as a selective barrier to regulate the flow of water and nutrients.

3. **Pericycle Formation**:
- The pericycle is described as being formed by a few layers of thick-walled parenchymatous cells.
- In dicot roots, the pericycle is indeed made up of parenchyma and can contribute to the formation of lateral roots.

4. **Pith Characteristics**:
- The pith is described as small or inconspicuous.
- In dicot roots, the pith is often reduced or even absent, which aligns with this description.

5. **Vascular Tissue Arrangement**:
- The presence of conjunctive tissue and 2 to 4 xylem and phloem patches indicates a specific arrangement of vascular tissues.
- Dicot roots typically have a limited number of xylem and phloem bundles (usually 2 to 4), which corresponds with the features provided.

### Conclusion:
Based on the analysis of all the characteristics, the structure described corresponds to a **Dicot Root**.
