Root cap is absent in

Options

A. Halophytes
B. Hydrophytes
C. Xerophytes
D. Homophytes

Answer

To determine where the root cap is absent, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understand the Root Cap**: The root cap is a protective structure at the tip of a plant root. It helps in protecting the growing tip of the root as it pushes through the soil.

2. **Analyze Option A - Halophytes**:
- Halophytes are salt-tolerant plants that thrive in saline environments.
- They have root caps to protect their roots as they grow in challenging conditions.
- **Conclusion**: Root caps are present in halophytes.

3. **Analyze Option B - Hydrophytes**:
- Hydrophytes are aquatic plants that live in water.
- They do not require a root cap because they do not need to penetrate soil; instead, they are submerged or floating in water.
- **Conclusion**: Root caps are absent in hydrophytes.

4. **Analyze Option C - Xerophytes**:
- Xerophytes are plants adapted to dry environments.
- They have root caps to protect their roots as they grow in arid conditions.
- **Conclusion**: Root caps are present in xerophytes.

5. **Analyze Option D - Homophytes**:
- The term "homophytes" is not commonly used in botanical classification. It may refer to a specific group of plants, but generally, it’s not recognized as a distinct category like the others.
- Without specific information, we cannot definitively state whether root caps are present or absent in homophytes.
- **Conclusion**: Uncertain, but likely root caps are present as they are common in most plants.

### Final Answer:
The root cap is absent in **Option B - Hydrophytes**.
