The upcoming discussion will update you about the difference between gymnosperms and angiosperms.
Difference # Gymnosperms:
1. In gymnosperms, vessels are absent (except Gnetales) in the xylem.
2. In gymnosperms, phloem lacks companion cells.
3. The so-called flowers of most of the gymnosperms are simple and unisexual in gymnosperms
4. In gymnosperms, ovules are naked i.e. not enclosed in carpel.
5. Pollen grains land directly upon the ovule after pollination in gymnosperms.
6. In gymnosperms, pollination takes place only by wind.
7. Cones are of usual occurrence in gymnosperms
8. In gymnosperms, archegonia are present (except Gnetales).
9. Double fertilization is absent in gymnosperms.
10. In gymnosperms endosperm is haploid tissue.
11. Fruit formation is absent in gymnosperms.
Difference # Angiosperms:
1. In angiosperms, vessels are present in the xylem.
2. In angiosperms, companion cells are present.
3. Flowers contain calyx and corolla and may be unisexual or bisexual in angiosperms.
4. In angiosperms, ovules are not naked. They are always enclosed within the ovary.
5. Pollen grains first fall on the stigma after pollination in angiosperms.
6. In angiosperms, pollination takes place by various agencies such as insects, wind, water, animals, etc.
7. Cones are not of usual occurrence in angiosperms.
8. In angiosperms, archegonia are absent.
9. Double fertilization is present as a rule in angiosperms.
10. In angiosperms, endosperm is usually triploid.
11. Fruit formation is present in angiosperms.
