Cycas and Adiantum resemble each other in having

Options

A. Motile sperms
B. Cambium
C. Vessles
D. Seeds

Answer

To determine the common feature between Cycas and Adiantum, we need to analyze the characteristics of both plants step by step.

### Step-by-Step Solution:

1. **Identify the Types of Plants:**
- **Cycas:** Cycas is classified as a gymnosperm. Gymnosperms are non-flowering plants that produce seeds that are not enclosed in an ovary (naked seeds).
- **Adiantum:** Adiantum is classified as a pteridophyte, which is a type of vascular plant that reproduces via spores and does not produce seeds.

2. **Examine the Features:**
- **Motile Sperm:** Both Cycas and Adiantum have motile sperm. This means that their sperm cells can move, which is a characteristic of certain groups of plants, including some gymnosperms and pteridophytes.
- **Cambium:** Cambium is a type of tissue that allows for secondary growth (thickening) in plants. It is present in gymnosperms like Cycas but is absent in pteridophytes like Adiantum.
- **Vessels:** Vessels are specialized structures for water transport. They are present in angiosperms but absent in both Cycas and Adiantum.
- **Seeds:** Seeds are a defining feature of gymnosperms. Cycas produces seeds, while Adiantum does not produce seeds, as it reproduces via spores.

3. **Conclusion:**
- The only common feature between Cycas and Adiantum is the presence of motile sperm. Therefore, the correct answer to the question is that Cycas and Adiantum resemble each other in having motile sperm.

### Final Answer:
Cycas and Adiantum resemble each other in having motile sperm.
