Detailed explanation-1: -Gymnosperms have naked seeds, angiosperms have enclosed seeds.
Detailed explanation-2: -As stated before, both gymnosperms and angiosperms are seed-bearing plants. Along with ferns and their allies, seed plants are vascular plants, which means they have xylem and phloem to transport water and nutrients.
Detailed explanation-3: -Gymnosperms are a smaller, more ancient group, and it consists of plants that produce “naked seeds” (seeds that are not protected by a fruit).
Detailed explanation-4: -The ovules in angiosperms are encased in an ovary, not exposed on the sporophylls of a strobilus, as they are in gymnosperms. Angiosperm means “covered seed". The ovules develop into seeds, and the wall of the ovary forms a fruit to contain those seeds. Fruits attract animals to disperse the seeds.
Detailed explanation-5: -A) An ovule is a plant structure that gives rise to a seed when fertilized. Both gymnosperms and angiosperms contain ovules.
