Detailed explanation-1: -Gymnosperms produce seeds (Figure 8.1. 1) and, together with flowering plants, constitute the seed plants. Although gymnosperms do not produce flowers and fruits, they still have embryos enclosed in a protective barrier or seed coat.

Detailed explanation-2: -Seed plants are classified into two classes depending on whether or not their seeds have coverings. Gymnosperms are vascular plants that develop uncovered seeds. The main group of gymnosperms is the conifer. Conifers produce seeds in cones.

Detailed explanation-3: -Angiosperms, are also known as flowering plants and having seeds enclosed within their fruit. Whereas gymnosperms have no flowers or fruits and have naked seeds on the surface of their leaves.

Detailed explanation-4: -Gymnosperms are a smaller, more ancient group, and it consists of plants that produce “naked seeds” (seeds that are not protected by a fruit). There are more than 1, 000 species of gymnosperms still found on Earth. The key difference between angiosperms and gymnosperms is how their seeds are developed.

Detailed explanation-5: -Gymnosperms are plants that have seeds but no flowers. The seeds of these plants are on cones or in cups. Most gymnosperms are evergreen. Gymnosperms include conifers, cycads and the ginkgo.
