Detailed explanation-1: -Angiosperms are plants which are vascular. Stems, stems, and leaves are in them. Angiosperm seeds are discovered in a flower, unlike gymnosperms such as conifers and cycads.

Detailed explanation-2: -Fern does not belong to the Gymnosperm. Cycas, Pinus and Ginkgo are the examples of Gymnosperm. Fern is an example of Pteridophytes. Pteridophytes are the first terrestrial plants to have vascular tissue which serves the purpose of transportation of food and water to various parts of the plants.

Detailed explanation-3: -Taxonomists recognize four distinct divisions of extant (nonextinct) gymnospermous plants-Pinophyta, Cycadophyta, Ginkgophyta, and Gnetophyta-with 88 genera and more than 1, 000 species distributed throughout the world.

Detailed explanation-4: -The gymnosperms are classified as-Cycadophyta, Ginkophyta, Gnetophyta, Coniferophyta.

Detailed explanation-5: -Gymnosperms are vascular plants of the subkingdom Embyophyta and include conifers, cycads, ginkgoes, and gnetophytes. Some of the most recognizable examples of these woody shrubs and trees include pines, spruces, firs, and ginkgoes.
