The answers are -seed-bearing and -vascular. The gymnosperms are a group of seed-bearing vascular plants. The name "gymnosperm" is derived from Greek words meaning "naked seeds" because their seeds do not develop within an ovary but on the surface of scales. The gymnosperms, as other vascular plants, have vascular tissue specialised to transport fluids. This group of plants includes conifers, Ginkgo, cycads, and gnetophytes.
