Secret Revealed: The Group That Is the Seed Plant and Changed the World!

YOGYAKARTA - For those who are focusing on studying biology, have you ever wondered, which group is the seed plant and why are they so important?

In fact, seed plants are a pillar of biodiversity, allowing plants to reproduce without water.

This group of plants has dominated the Earth's landscape for millions of years. Through the evolution of seeds, they achieved an incredible ability to adapt to various environments.

Why Are Seeds So Important?

Seed plants, known scientifically as Spermatophyta, are a group of plants that rely on seeds as their main means of reproduction.

Well, this name comes from the Greek, sperma which means "seed" and phyton which means "plant." You need to know, the seed itself is the main structure that carries the embryo after the fertilization process.

Thanks to the evolution of seeds, this group was able to survive and thrive widely in various terrestrial habitats. Amazingly, there are around 352,000 species of Spermatophyta in the world, and Indonesia contributes around 9% of the total diversity!

Three Main Secrets of Seed Plants

The interesting fact is that seed plants have a much more complex and organized structure compared to other groups of ancient plants, such as mosses or ferns.

In addition, the parts of the seed plant are also clearly divided into roots, stems, and true leaves. However, there are three key characteristics that make it superior, among which are:

Seeds as the Main Reproduction

Seeds are a fundamental distinguishing feature, ensuring the survival of the species.

The Complex Vascular Network

They have a sophisticated transport network (vascular), namely the xylem that transports water and the phloem that channels the results of photosynthesis. It is this strong vascular system that allows the seed plants to grow tall and large.

Special Reproductive Tools

Sexual reproduction is carried out through Flowers (in the closed-seeded group) or Strobilus (stalk) in the open-seeded group.

The Group Which Is a Seed Plant

Meanwhile, the group that is a seed plant is divided into two large factions that dominate nature, namely:

Gymnospermae (Open Seeds)

This group is also called the pioneers. Gymnospermae comes from the word gymnos which means naked, because their seeds are not covered or protected by the fruit.

This group is generally in the form of large trees, has a woody stem, and does not produce true flowers. Instead, their reproductive organs are in the form of a strobilus or a bundle. Examples are the Damar tree, Pinus, Fir, and Haji fern.

Angiospermae (Closed Seed)

This second type is the most modern group we know. Angiosperms are called closed-seeded because their seeds are protected inside the fruit, which later develops into a delicious fruit.

The main characteristic of angiosperms is having flowers as a generative reproductive tool. This type is further divided based on the seed coat, namely Monocotyledon (such as rice and corn) and Dicotyledon (such as mango and chili).

Seed Plants as an Economic Pillar and Earth Protector

As an economic pillar, seed plants are the main source of the world's food (from staple foods such as rice and wheat, to vegetables and fruits). Then in the clothing sector, cotton fiber is the raw material for clothing.

In addition, the industry also relies on them for paper raw materials (pine), oil (palm oil), and high-quality wood (teak, mahogany) for buildings and furniture. In fact, cloves and ginkgo provide important benefits in the world of medicine.

Ecologically, the roots of seeded plants also help prevent soil erosion and reduce the risk of disasters. In addition, through photosynthesis, they act as a carbon dioxide (CO₂) absorber and produce oxygen (O₂), playing an active role in reducing global warming and maintaining the balance of ecosystems.

With its vital role, the group of seed plants is the key to the ecosystem. By understanding the role of spermatophyta, it can help us manage natural resources as a source of food, clothing, and environmental protection.
