Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers) and angiosperms (flowering plants). All gymnosperms and many angiosperms are woody plants. They are commonly found in both gymnosperms and angiosperms. It consumes a large variety of gymnosperms and angiosperms. Instead, correlations can be made between the number of extant gymnosperms and angiosperms. The monocots are one of the major divisions of the flowering plants or angiosperms. In monocots the hypophyll tends to be the dominant part in contrast to other angiosperms. Double fertilization is a complex fertilization mechanism of flowering plants (angiosperms). Seagrasses are flowering plants (angiosperms) which grow in marine environments. Most of the recent phytophagous species of Coleoptera feed on flowering plants or angiosperms. The flower is the characteristic structure concerned with sexual reproduction in flowering plants (angiosperms). The radiation of herbaceous angiosperms occurred much later. Pollen grains from living pinophyte species produce pollen tubes, much like those of angiosperms. More recently proprioception has also been described in flowering land plants (angiosperms). About 80% of angiosperms rely on biotic pollination.
