The main differences between pteridophytes and gymnosperms are that in pteridophytes secondary growth is absent but in gymnosperms it is present.
Second is male gametes are ciliate in pteridophytes while they are absent in gymnosperms, they have seeds or ovules.

Difference Between Gymnosperms and Pteridophytes
Gymnosperms and pteridophytes are two distinct groups of plants that exhibit various characteristics. The significant difference highlighted in this context pertains to the presence of ovules.
Key Characteristics of Gymnosperms
- Gymnosperms are a group of seed-producing plants that include conifers, cycads, and gnetophytes.
- They are characterized by the presence of seeds that are not enclosed in an ovary, hence the term "gymnosperm," meaning "naked seeds."
- Gymnosperms produce ovules on the surface of their reproductive structures, specifically in cones or strobili.
Key Characteristics of Pteridophytes
- Pteridophytes encompass ferns, horsetails, and clubmosses, which are seedless vascular plants.
- They reproduce via spores rather than seeds, with no ovules present.
- Pteridophytes have a life cycle that includes both a dominant sporophyte and a gametophyte stage.
Importance of Ovules in Gymnosperms
- The presence of ovules is a defining feature of gymnosperms. Ovules develop into seeds after fertilization, allowing for the protection and nourishment of the developing embryo.
- This adaptation provides gymnosperms with a reproductive advantage, enabling them to thrive in diverse environments.
Conclusion
In summary, gymnosperms differ from pteridophytes primarily in their reproductive structures, particularly the presence of ovules. This characteristic is significant as it allows gymnosperms to produce seeds, enhancing their survival and reproductive success compared to pteridophytes, which rely solely on spores.
