Phanerograms without the ovaries are

The correct option is gymnosperms.

To understand why this is the correct answer, let us break down the botanical terms step-by-step:

1. What are Phanerogams?
Phanerogams (also known as spermatophytes) are plants that produce seeds. This group is distinguished from cryptogams (like algae, mosses, and ferns), which do not produce seeds. Phanerogams are broadly classified into two main groups:
- Gymnosperms
- Angiosperms

2. Gymnosperms vs. Angiosperms:
- Angiosperms are flowering plants. In angiosperms, the seeds are enclosed inside an ovary, which later matures into a fruit. Therefore, they have ovaries.
- Gymnosperms are non-flowering seed plants. The term "gymnosperm" literally translates to "naked seeds" (from Greek gymnos meaning naked, and sperma meaning seed). In these plants, the ovules are not enclosed by an ovary wall. Because they lack an ovary, they do not produce flowers or true fruits, and their seeds are borne exposed on the surfaces of reproductive structures like cones.

Conclusion:
Since gymnosperms are seed-producing plants (phanerogams) that lack an ovary, the group of phanerogams without ovaries is gymnosperms.
