- Gymnosperms were the first seed plants and they bear their ovules and seeds exposed. The ovules are on scales, which are arranged in the cone-like structures.
- Gymnosperms lack the folded, marginally-sealed carpels that characterize flowering plants. Angiosperms have ovules that are enclosed in a carpel.
- In Gymnosperms, the pollen-receptive structures are the ovules, rather than the stigma portion of the carpels, as in angiosperms.
- Most gymnosperms lack vessels in the xylem but possess tracheids. Angiosperms have both vessels and tracheids.
