As we go from periphery to the center of a dicot root , the correct order of tissues that we will encounter is
(a) Epiblema - Cortex - Endodermis - Metaxylem - Protoxylem - Pith
(b) Cortex - Epiblema - Endodermis - Metaxylem - Protoxylem - Pith
(c) Cortex - Epiblema - Endodermis - Protoxylem - Metaxylem - Pith
(d) Epiblema - Cortex - Endodermis - Protoxylem - Metaxylem - Pith

Options

A. Epiblema - Cortex - Endodermis - Metaxylem - Protoxylem - Pith
B. Cortex - Epiblema - Endodermis - Metaxylem - Protoxylem - Pith
C. Cortex - Epiblema - Endodermis - Protoxylem - Metaxylem - Pith
D. Epiblema - Cortex - Endodermis - Protoxylem - Metaxylem - Pith

Answer

To determine the correct order of tissues encountered when moving from the periphery to the center of a dicot root, we can analyze the structure of the dicot root step by step.

### Step-by-Step Solution:

1. **Identify the Outermost Layer**:
- The outermost layer of a dicot root is known as the **epiblema** (or rhizodermis). This layer is responsible for the absorption of water and minerals.

2. **Next Layer - Cortex**:
- Beneath the epiblema is the **cortex**. This tissue is composed of parenchyma cells and serves as storage and transport.

3. **Endodermis**:
- Following the cortex, we encounter the **endodermis**. This layer is crucial as it regulates the movement of water and nutrients into the vascular system.

4. **Protoxylem**:
- After the endodermis, we find the **protoxylem**. This is the first-formed xylem tissue that conducts water and minerals.

5. **Metaxylem**:
- Next, we have the **metaxylem**, which is formed later and has larger vessels compared to protoxylem. It also conducts water and minerals.

6. **Pith**:
- Finally, at the center of the root, we have the **pith**, which is a central tissue that may store nutrients.

### Conclusion:
Based on the above analysis, the correct order of tissues from the periphery to the center of a dicot root is:
**Epiblema - Cortex - Endodermis - Protoxylem - Metaxylem - Pith**.

Thus, the correct answer is **(d) Epiblema - Cortex - Endodermis - Protoxylem - Metaxylem - Pith**.
