Seed plants are divided into

Seed plants are divided into two main groups: angiosperms and gymnosperms. Angiosperms are flowering plants that produce seeds inside a protective fruit. This group includes a wide variety of plants, such as roses, lilies, tomatoes, and oak trees. Gymnosperms are non-flowering plants that produce seeds without a protective covering. This group includes conifers, such as pine trees, and cycads, which are a type of primitive seed plant. So, in summary, seed plants can be classified into angiosperms and gymnosperms based on the type of seed and its protective covering.
