Gymnospermic plants are:-

Options

A. Homosporous
B. Heterosporous
C. Both
D. Without spores

Answer

**Step-by-Step Solution:**

1. **Understanding Gymnosperms**: Gymnosperms are a group of seed-bearing plants that include conifers, cycads, ginkgo, and gnetophytes. They are characterized by having seeds that are not enclosed in an ovary (unlike angiosperms).

2. **Types of Spores**: In plant biology, plants can be classified based on their spore production into two categories: homosporous and heterosporous.
- **Homosporous** plants produce one type of spore that develops into a gametophyte that can produce both male and female gametes.
- **Heterosporous** plants produce two different types of spores: microspores (which develop into male gametophytes) and megaspores (which develop into female gametophytes).

3. **Identifying Gymnosperms' Spore Type**: Gymnosperms are classified as heterosporous because they produce two types of spores:
- **Microspores**: These are produced in smaller cones and develop into pollen grains (male gametophytes).
- **Megaspores**: These are produced in larger cones and develop into female gametophytes.

4. **Conclusion**: Based on the classification of spores, we can conclude that gymnospermic plants are heterosporous.

5. **Final Answer**: Therefore, the correct answer to the question "Gymnospermic plants are:" is **heterosporous** (Option 2).
