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 reproductive structures and the type of seeds they produce.

2. **Etymology of the Term "Gymnosperm"**: The term "Gymnosperm" comes from Greek words where "gymnos" means naked and "sperma" means seed. This indicates that the seeds of these plants are not enclosed in an ovary.

3. **Seed Development in Gymnosperms**: In Gymnosperms, the ovules are exposed and are not surrounded by any ovary wall. This means that when fertilization occurs, the seeds that develop remain exposed and are referred to as "naked seeds."

4. **Absence of Fruits**: Since the seeds are not enclosed within an ovary, Gymnosperms do not produce true fruits. Fruits typically develop from the ovary wall after fertilization, but in Gymnosperms, this structure is absent.

5. **Examples of Gymnosperms**: Common examples of Gymnosperms include Cycas, Pinus, and Cedrus. These plants exemplify the characteristics of Gymnosperms, particularly the presence of naked seeds.

6. **Conclusion**: Therefore, Gymnosperms are named so because of the presence of naked seeds, which is the defining characteristic of this group of plants.

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