Seeds and vascular systems. Ferns do not have seeds and have a primitive vascular system, while pine trees have seeds and a more advanced vascular system.

Ferns and pine trees can be classified as different organisms from each other based on whether they have flowers and seeds.

1. Flowers: Ferns do not have flowers. They reproduce by spores, which are small, single-celled structures. In contrast, pine trees have flowers, which are reproductive structures that contain the plant's male and female reproductive parts.

2. Seeds: Ferns do not produce seeds. Instead, they reproduce by spores. On the other hand, pine trees, like most other plants, produce seeds as part of their reproductive cycle. Seeds are structures that contain the embryo of the plant and are capable of developing into a new individual under suitable conditions.

In addition to these two differences, another way to differentiate between ferns and pine trees is their vascular system:

3. Vascular system: Both ferns and pine trees have a vascular system, which consists of tissues specialized for transporting water and nutrients within the plant. This system allows them to grow larger in size compared to non-vascular plants like mosses.
