Answer:
D. Both reproduce sexually, but gymnosperms produce pollen cones and seed cones and angiosperms produce flowers or fruit.
Step-by-step explanation:
Higher plants are grouped into two namely; gymnosperms and angiosperms. Gymnosperms and angiosperms are both vascular seed-bearing plants that make use of sexual reproduction to produce their seeds.
One major difference between the gymnosperms and angiosperms is the way by which they produce their seeds. Angiosperms produce their seeds, which forms from an ovary of a flower, in an enclosure called FRUIT. This is why they are called FLOWERING PLANTS.
On the other hand, gymnosperms produce their seeds on naked structures called CONES. Hence, although they both reproduce sexually, but gymnosperms produce pollen cones and seed cones while angiosperms produce flowers or fruit.
