Detailed explanation-1: -Gymnosperms – plants with cones. Angiosperms – plants with flowers.

Detailed explanation-2: -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.

Detailed explanation-3: -Gymnosperms are a relatively small group of plants that do not flower and bear “naked seeds.” This means that the seeds are produced on the surface of the reproductive structure, rather than enclosed within it as in a fruit.

Detailed explanation-4: -Angiosperms are vascular plants. They have stems, roots, and leaves. Unlike gymnosperms such as conifers and cycads, angiosperm’s seeds are found in a flower. Angiosperm eggs are fertilized and develop into a seed in an ovary that is usually in a flower.

Detailed explanation-5: -They are a group of vascular plants with naked (without ovary) seeds. Gymnospems are also heterosporous. Furthermore, gymnosperms produce two different types of cones, namely, large female cones and small male cones. Four groups of gymnosperms are known: CYCADOPHYTA: 100 cycad species (cycad, sago palm)
