Besides normal roots , Cycas possesses another type of roots near the soil surface and called

Options

A. Surface feeders
B. Coralloid
C. Mycorrhiza
D. Adventitious

Answer

To answer the question regarding the type of roots that Cycas possesses near the soil surface, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a specific type of root found in Cycas, in addition to the normal roots.

2. **Analyzing the Options**: We have four options to consider:
- Option 1: Surface feeder
- Option 2: Coralloid
- Option 3: Mycorrhiza
- Option 4: Adventitious

3. **Evaluating Each Option**:
- **Option 1: Surface feeder** - This term typically refers to certain fish that feed on organisms at the water's surface. It does not pertain to a type of root, so this option is incorrect.
- **Option 2: Coralloid** - Coralloid roots are specialized roots that contain cyanobacteria (blue-green algae) which help in nitrogen fixation. These roots are indeed found near the soil surface in Cycas, making this option correct.
- **Option 3: Mycorrhiza** - Mycorrhiza refers to a symbiotic relationship between fungi and plant roots, where the plant provides sugars to the fungus, and the fungus supplies water and nutrients to the plant. While this is an important root association, it does not specifically refer to a type of root found near the surface in Cycas.
- **Option 4: Adventitious** - Adventitious roots arise from unusual places such as stems or leaves, rather than from the root system. This option does not apply to the specific type of root in question.

4. **Conclusion**: After evaluating all options, the correct answer is **Option 2: Coralloid**. These roots are characteristic of Cycas and are located near the soil surface.

### Final Answer:
**Coralloid**
