**Plant that bears seeds but not fruit: Selaginella or Pinus?**

**Introduction:**
In the plant kingdom, there are various types of plants that reproduce through different mechanisms. Some plants produce seeds as their means of reproduction, while others produce fruits containing seeds. However, there are certain plants that bear seeds but do not produce fruits. Two such examples are Selaginella and Pinus.

**Selaginella:**
Selaginella is a genus of plants commonly known as spikemosses. These plants belong to the division Lycopodiophyta and reproduce through spores, not seeds. They have an ancient lineage and are considered to be a primitive group of plants. Selaginella plants possess specialized structures called strobili, which produce spores. These spores are dispersed in the environment and give rise to new plants. Thus, Selaginella plants do not produce fruits or seeds.

**Pinus:**
Pinus, commonly known as pine trees, are a genus of plants belonging to the division Pinophyta. Pine trees reproduce through seeds, but they do not produce fruits in the traditional sense. Instead, they bear cones, which are woody structures that contain seeds. These cones develop on the branches of pine trees and protect the developing seeds. Once the seeds are mature, the cones open up, and the seeds are dispersed by wind, animals, or gravity. Therefore, while Pinus plants do not produce fruits, they do produce seeds within their cones.

**Comparison:**
1. Reproductive Mechanism:
- Selaginella: Reproduces through spores, not seeds.
- Pinus: Reproduces through seeds contained within cones.

2. Structures:
- Selaginella: Possesses strobili, which produce spores.
- Pinus: Bears cones that contain seeds.

3. Reproductive Output:
- Selaginella: Does not produce fruits or seeds.
- Pinus: Produces seeds within cones.

**Conclusion:**
In conclusion, Selaginella and Pinus are two examples of plants that bear seeds but do not produce fruits. Selaginella reproduces through spores, while Pinus reproduces through seeds contained within cones. Understanding the reproductive mechanisms of different plant species allows us to appreciate the diversity and complexity of the plant kingdom.
