Cycas resembles angiosperms in having

Options

A. Vessels
B. Circinate vernation
C. Siphonogany
D. Dichotomous branching.

Answer

**Step-by-Step Solution:**

1. **Understanding Cycas**: Cycas is a genus of plants that belongs to the group known as cycads. They are considered gymnosperms, which means they produce seeds that are not enclosed in an ovary (naked seeds).

2. **Comparing Cycas and Angiosperms**: Angiosperms, or flowering plants, are characterized by having seeds enclosed within a fruit. Despite this difference, Cycas shares some reproductive features with angiosperms.

3. **Identifying Key Features**: The question asks for a feature that Cycas resembles in angiosperms. The options provided are:
- a. Vessels
- b. Circinate vernation
- c. Siphonogamy
- d. Dichotomous branching

4. **Analyzing the Options**:
- **Vessels**: Angiosperms have vessels in their xylem, while cycads typically do not.
- **Circinate Vernation**: This refers to the coiled arrangement of young leaves, which is a characteristic of cycads but not a feature that links them to angiosperms.
- **Siphonogamy**: This term refers to the process where pollen tubes are formed to transport male gametes to the ovule. This is a feature seen in both Cycas and angiosperms.
- **Dichotomous Branching**: This is a growth pattern seen in some plants, but it does not specifically relate Cycas to angiosperms.

5. **Conclusion**: Among the options, the feature that Cycas shares with angiosperms is **Siphonogamy**. This is the correct answer.

**Final Answer**: c. Siphonogamy
