Pinus is classified under Gymnosperms because

Options

A. It is large tree
B. it is pollinated by wind
C. It has exposed ovules
D. It produces seeds and it has narrow leaves

Answer

**Step-by-Step Solution:**

1. **Understanding Gymnosperms**: Gymnosperms are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes. They are characterized by having seeds that are not enclosed in an ovary.

2. **Identifying Key Characteristics**: The defining feature of Gymnosperms is the presence of naked ovules. This means that the ovules are exposed and not enclosed within a fruit, which is a characteristic that distinguishes them from Angiosperms (flowering plants).

3. **Analyzing Pinus**: Pinus, commonly known as pine trees, belong to the group of conifers. They produce seeds that are not enclosed in an ovary, which means they have exposed ovules.

4. **Pollination Method**: Pinus is primarily wind-pollinated, which is a common trait among Gymnosperms. While some Angiosperms can also be wind-pollinated, this characteristic alone does not classify a plant as a Gymnosperm.

5. **Conclusion**: The classification of Pinus under Gymnosperms is primarily due to the presence of exposed ovules, which are a hallmark of this group of plants. Therefore, the correct reason for classifying Pinus as a Gymnosperm is that it has naked seeds (exposed ovules).

**Final Answer**: Pinus is classified under Gymnosperms because it has exposed ovules (naked seeds).
