Detailed explanation-1: -Gymnosperms have an advanced root foundation and are made up of vascular tissues, whereas pteridophytes are divided into root systems, stalks, and leaflets. In pteridophytes, the main part of evolution i.e the seed is missing. Hence, gymnosperms are viewed as further developed.

Detailed explanation-2: -Advanced-Gymnosperm are a group of plants that are more advanced than Pteridophyta. 2. Seed production-Gymnosperm plants produce seeds, which is an advanced trait.

Detailed explanation-3: -Unlike bryophytes and pteridophytes, in gymnosperms the male and the female gametophytes do not have an independent free-living existence. They remain within the sporangia retained on the sporophytes. Pteridophytes have free living, photosynthetic thalloid gametophyte called prothallus.

Detailed explanation-4: -They are the most advanced plants with well-differentiated plant bodies, developed vascular systems, and bear seeds covered within fruits. The significant difference between bryophytes pteridophytes gymnosperms and angiosperms is the seed-bearing capacity.
