The higher diversity indicated the angiosperms are adaptive to terrestrial ecosystems. The name is based on the unenclosed condition of their seeds (called ovules in their unfertilized state). The flowering plants in the narrow sense (angiosperms) are a group of the seed plants (spermatophytes).Extant angiosperms are seen as a relatively young diversification, the “crown group” of an older clade, the “stem group” angiophytes, without well-established fossils and without surviving branches other than the angiosperms (Fig. Endosperm in gymnosperm is formed Angiosperms possess seeds enclosed in a fruit, unlike gymnosperms. a paraphyletic grouping.
