Which of the following is correct sequence of layers in typical monocot root (from outer surface to inside)
(a) Epiblema, endodermis, cortex, pericycle
(b) Pericycle, cortex, endodermis, epiblema
(c) Epiblema, cortex, endodermis, pericycle
(d) Epiblema, pericycle, cortex, endodermis

Options

A. Epiblem, endodermis, cortex, pericycle
B. Pericycle, corted, endodermis, epiblema
C. Epiblems, cortex, endodermis, percycle
D. Epiblems, pericycle, cortex, endodermis

Answer

To determine the correct sequence of layers in a typical monocot root from the outer surface to the inside, we need to identify the layers present in the monocot root and their order.

### Step-by-Step Solution:

1. **Identify the Layers**: In a typical monocot root, the layers from the outermost to the innermost are:
- **Epiblema**: This is the outermost layer, also known as the epidermis.
- **Cortex**: This layer is located just beneath the epiblema and is responsible for storage and transport of nutrients.
- **Endodermis**: This is the innermost layer of the cortex, which regulates the flow of water and nutrients into the vascular system.
- **Pericycle**: This layer is located just inside the endodermis and is involved in the formation of lateral roots.

2. **Arrange the Layers**: Based on the identification, the correct order from the outer surface to the inside is:
- Epiblema → Cortex → Endodermis → Pericycle

3. **Evaluate the Options**:
- (a) Epiblema, endodermis, cortex, pericycle: Incorrect order.
- (b) Pericycle, cortex, endodermis, epiblema: Incorrect order.
- (c) Epiblema, cortex, endodermis, pericycle: Correct order.
- (d) Epiblema, pericycle, cortex, endodermis: Incorrect order.

4. **Conclusion**: The correct sequence of layers in a typical monocot root from outer surface to inside is given in option (c) Epiblema, Cortex, Endodermis, Pericycle.

### Final Answer:
The correct sequence is (c) Epiblema, Cortex, Endodermis, Pericycle.
