Gymnosperms are seed-bearing plants. The flowers are one of the most differentiating features of angiosperms. Whereas gymnosperms have no flowers or fruits and have naked seeds on the surface of their leaves. However, mitotic division still follows meiosis in the sporophyte, resulting in a multicellular gametophyte, which produces eggs or sperm. Sepals enclose and protect the flower bud before it opens. Hence, angiosperms are considered better than gymnosperms. The vast array of ferns reproduce through spores, instead of seeds. University of Cincinnati; Angiosperms; J.Stein Carter; Nov. 2, 2004. As the walls of ovaries begin to thicken, they combine to form a single fruit. Within the seeds are an embryo sporophyte that grows into a mature sporophyte. She has her M.S. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.

Instead of being enclosed in fruits, their seeds are found in unisexual cones and are not visible until they reach maturity. Campbell Biology. Gymnosperms are seed plants adapted to life on land; thus, they are autotrophic, photosynthetic organisms that tend to conserve water. In Kingdom Plantae, plant species are classified according to their method of reproduction. 2. They have several traits in common with angiosperms, such as vessel elements in the xylem, double fertilization, and a covering over their seeds (more on this in labs 21 and 22). Angiosperms and gymnosperms are classifications of plants that have different characteristic properties. I hope this guide has provided you with all the information regarding these two different plant types.
