Gymnosperm are named so because of the presence of

Options

A. winged seeds
B. true fruits
C. non-motile male gametes
D. naked seeds

Answer

**Step-by-Step Solution:**

1. **Understanding Gymnosperms**: Gymnosperms are a group of seed-producing plants that include conifers, cycads, and ginkgo. They are characterized by their seeds being exposed or "naked," meaning they are not enclosed in a fruit.

2. **Analyzing the Options**: The question provides four options:
- Option 1: Winged seed
- Option 2: True fruit
- Option 3: Non-motile male gamete
- Option 4: Naked seed

3. **Identifying the Correct Answer**: The term "Gymnosperm" itself is derived from Greek, meaning "naked seed." This indicates that the defining characteristic of gymnosperms is the presence of seeds that are not enclosed in an ovary or fruit. Therefore, the correct answer is:
- **Option 4: Naked seed**

4. **Understanding the Classification**: Gymnosperms belong to the category of Phanerogams, which are seed-producing plants. They are different from Cryptogams, which do not produce seeds.

5. **Characteristics of Gymnosperms**: Gymnosperms are also known as softwood spermatophytes because they lack xylem vessels, which are typically found in angiosperms (flowering plants). This absence of vessels contributes to their softer wood structure.

6. **Conclusion**: Based on the analysis, we conclude that gymnosperms are named for their "naked seeds," which is a fundamental characteristic that distinguishes them from other plant groups.

**Final Answer**: Gymnosperms are named so because of the presence of **naked seeds**.
