Answer:

Both the sunflower and gingko have seeds.

A gymnosperm refers to plants whose seeds are borne on the female cones and seeds are not enclosed in a fruit wall. The gymnosperms comprise of coniferales, cycadales and ginkgoales. Both the sunflower (angiosperm) and ginkgo (gymnosperm) are seed-producing plants. However, the seeds of a sunflower are enclosed by a flower or a fruit wall, while in case of Ginkgoales they are not. Also, sunflowers include double fertilization, while the Ginkgoales involve only a single fertilization.
