Cycas is a gymnosperm because of

Options

A. Vessels present in xylem
B. Living fossil
C. Naked seed without fruit
D. None of the above.

Answer

**Step-by-Step Solution:**

1. **Understanding Cycas**: Cycas is a type of plant that belongs to the group known as gymnosperms. Gymnosperms are characterized by their seed structure and reproductive methods.

2. **Identifying Key Characteristics of Gymnosperms**: One of the defining features of gymnosperms is that they produce "naked seeds." This means that their seeds are not enclosed within a fruit. Instead, they are exposed and can be directly pollinated.

3. **Comparing with Angiosperms**: In contrast to gymnosperms, angiosperms (flowering plants) have seeds that are enclosed within fruits. This difference is crucial in classifying plants into these two groups.

4. **Analyzing the Options**:
- **Option A**: Vessels present in xylem - This is not a characteristic of gymnosperms as they typically have tracheids instead of vessels.
- **Option B**: Living fossil - While Cycas is often referred to as a "living fossil," this term does not specifically define it as a gymnosperm.
- **Option C**: Naked seeds without fruit - This is the correct characteristic that defines Cycas as a gymnosperm.
- **Option D**: None of these - This option is incorrect as option C is valid.

5. **Conclusion**: Based on the characteristics of Cycas and the definitions of gymnosperms, the correct answer is option C: naked seeds without fruit.

**Final Answer**: C. Naked seeds without fruit.
