Final answer:
Ovaries and ovules are present in angiosperms but not in gymnosperms. Seeds and pollen are present in both angiosperms and gymnosperms.
Step-by-step explanation:
Angiosperms are plants that produce flowers and fruits, while gymnosperms do not. Among the options given, ovaries and ovules are present in angiosperms but not in gymnosperms. Ovaries are the female reproductive organs in flowers and contain ovules, which house the eggs. In many cases, after fertilization, ovaries develop into fruits, which help in seed dispersal.
On the other hand, seeds and pollen are present in both angiosperms and gymnosperms. Gymnosperms produce seeds in cones, and the seeds are attached to scales on the cones. Angiosperms also produce seeds, but they are enclosed within the ovaries of flowers.
