A characteristic of Cycas that resembles ferms is

Options

A. Circinate ptyxis
B. Sori in microsporophyll
C. Uniflagellate male gamete
D. Both A and B.

Answer

To solve the question regarding a characteristic of Cycas that resembles ferns, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Cycas and Ferns**:
- Cycas is a genus of cycads, which are seed-producing plants. Ferns are non-flowering vascular plants that reproduce via spores.

2. **Identifying Key Characteristics**:
- The question asks for a characteristic that Cycas shares with ferns. We need to analyze the options provided:
- A. Circinate Phyllotaxy
- B. Sori in Microphylls
- C. Uniflagellate male gamete
- D. Both A and B

3. **Analyzing Option A - Circinate Phyllotaxy**:
- Circinate phyllotaxy refers to the way young leaves (fronds) are coiled up and unfurl as they mature. This is a characteristic seen in both Cycas and ferns.

4. **Analyzing Option B - Sori in Microphylls**:
- Sori are clusters of sporangia found on the underside of fern leaves. While Cycas does not have true microphylls like some ferns, it does have structures that can resemble this feature.

5. **Analyzing Option C - Uniflagellate Male Gamete**:
- Uniflagellate male gametes are characteristic of certain groups of plants, but this is not a shared feature with ferns. Ferns typically have biflagellate sperm.

6. **Conclusion**:
- Since both A (Circinate Phyllotaxy) and B (Sori in Microphylls) are characteristics that Cycas shares with ferns, the correct answer is option D: Both A and B.

### Final Answer:
The characteristic of Cycas that resembles ferns is **D. Both A and B**.
