Detailed explanation-1: -Angiosperms are called flowering plants, whereas gymnosperms are called non-flowering plants. Angiosperms have seeds enclosed in an ovary (a fruit) whereas gymnosperms have no flowers or fruits and have naked seeds on the surface of leaves.

Detailed explanation-2: -Fern does not belong to the Gymnosperm. Cycas, Pinus and Ginkgo are the examples of Gymnosperm.

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: -Common types of gymnosperms are conifers, cycads, ginkgoes, and gnetophytes.

Detailed explanation-5: -Gymnosperms are seed-bearing vascular plants, such as cycads, ginkgo, yews and conifers, in which the ovules or seeds are not enclosed in an ovary. The word “gymnosperm” comes from the Greek word gymnospermos, meaning “naked seeds".
