The radicle in maize has two coverings

Options

A. outer coleorhiza and inner root cap
B. inner colerhiza and outer root cap
C. outer coleoptile and inner root cap
D. inner coleoptile and inner root cap

Answer

To solve the question regarding the coverings of the radicle in maize, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure of Maize Seed**:
- Maize (Zea mays) is a monocot seed, which means it has a specific structure that includes various parts such as the scutellum, coleoptile, radical, and coliorhiza.

2. **Understand the Components of the Embryo**:
- The embryo of maize consists of:
- **Scutellum**: The main part of the embryo.
- **Coleoptile**: The protective sheath covering the young shoot (plumule).
- **Radical**: The part that develops into the root.
- **Coliorhiza**: The protective covering of the radicle.

3. **Determine the Coverings of the Radicle**:
- The radicle in maize is covered by two structures:
- **Outer Covering**: Coliorhiza (the protective sheath around the radicle).
- **Inner Covering**: Root cap (which protects the growing tip of the root).

4. **Evaluate the Options Provided**:
- The options given in the question are:
1. Outer coliorhiza and inner root cap
2. Inner coliorhiza and outer root cap
3. Outer coleoptile and inner root cap
4. Inner coleoptile and inner root cap
- Based on our understanding, the correct answer is the first option: **Outer coliorhiza and inner root cap**.

5. **Conclusion**:
- Thus, the radicle in maize has two coverings: the outer covering is the coliorhiza, and the inner covering is the root cap.

### Final Answer:
The correct option is **1. Outer coliorhiza and inner root cap**.
