Antarctica is a very harsh environment, with extremely low temperatures, strong winds, and very little precipitation. This means that there are no trees or plants that grow from seeds in Antarctica.

However, there are some microorganisms that live in the soil and water of Antarctica. These include:

* Algae: These are simple plants that can survive in very cold and dry conditions.

* Lichens: These are a combination of algae and fungi that can grow on rocks and soil.

* Mosses: These are small, non-vascular plants that can survive in cold and damp environments.

These microorganisms are not technically "seeds," but they do reproduce and play an important role in the ecosystem of Antarctica.
