Detailed explanation-1: -2. Gymnosperms have naked seeds, angiosperms have enclosed seeds.

Detailed explanation-2: -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-3: -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-4: -The seed is the embryonic stage of the plant life cycle. Most seeds consist of three parts: embryo, endosperm, and seed coat. The embryo is a tiny plant that has a root, a stem, and one or more leaves. The endosperm is the nutritive tissue of the seed, often a combination of starch, oil, and protein.

Detailed explanation-5: -The gymnosperms have their ovules freely exposed before and after fertilization. They are not enclosed by any ovary wall. The seeds formed by them lack the seed coat. Hence, due to the absence of ovary wall and seed coat, their seeds are naked.
