B
Explanation
The term Gymnosperms is derived from the Greek words gymnos (naked) and sperma (seeds). In these plants, the ovules are not enclosed by any ovary wall and remain exposed, both before and after fertilization. Consequently, the seeds that develop are not covered, hence the name "naked seeds."
- Angiosperms are flowering plants where the seeds are enclosed within an ovary (which matures into a fruit).
- Pteridophytes (such as ferns) and Bryophytes (such as mosses) are primitive plants that do not produce seeds at all; they reproduce via spores.
Common examples of gymnosperms include Pinus, Cycas, and Cedrus.
