Which group of plants has seeds enclosed in an ovary?

• A. Ferns
• B. Mosses
• C. Angiosperms
• D. Gymnosperms

Answer: (C)

Seeds enclosed in an ovary occur in flowering plants, the angiosperms. In these plants, the ovary is part of the flower’s pistil, and after fertilization the ovary develops into a fruit that encases and protects the seeds, often aiding their dispersal. This is different from gymnosperms, which have seeds exposed on cone scales and are not enclosed by an ovary, and from mosses and ferns, which reproduce by spores rather than seeds. So, the group with seeds enclosed in an ovary is the angiosperms.
