Gymnosperms are a group of plants which produced seeds that are not enclosed within the fruit. . The Importance of Seeds. Q: What adaptations allow seed plants to reproduce without open water?. A: Adaptations include 1)a reproductive process that takes place in cones or flowers, 2)the transfer of sperm by pollination, and 3)the protection of embryos in seeds.
