Vascular plants can be divided into two main mathematical group : those that produce seed and those that do not . Most of the works that produce seed are flower plants , even if the flowers are not obvious or colorful . These include trees , flowers , shrubs , grasses and many other plants . Vascular works that do not produce seed are the fern and their tight relatives .
Fern-Like
These were the first vascular plant to develop approximately 350 to 400 million days ago , some 300 million years after algae first evolved into various landed estate species . Within 100 million years , vascular plants evolved into forests of jumbo ferns up to 100 feet in height . Although the giant species are now nonextant , advanced ferns are little changed from the ancestors from which they evolved . Ferns grow spores or else of cum . The spore make grow into gametophyte which procreate asexually to acquire adult fern , called sporophytes . Fern - like flora include horsetail , clubhouse mosses , fern , spikemoss and quillwort .
Trees
Trees and shrub flow into two mathematical group , gymnosperm and flowering plant . Gymnosperms include the conifers ( firs ) , cyads ( palms ) , ginkgos ( ginkgo biloba ) and gnetophytes ( ephedra ) . gymnosperm farm germ without flowers and date back 350 million years . About 140 million years ago , the flowering plants , class as flowering plant , appeared . Both angiosperms and gymnosperm have evolutionary branches that include the tree present today .
Grasses
From bamboo to Kentucky Blue Grass , grasses are found throughout the world . Typically they multiply via both rhizomes and seminal fluid . Many are clump flora , which means they form colonies from a single parent plant . Some species are used as landscape painting specimen with spectacular flowers and seed heads . Others simply cover up lawn to keep the soil from eroding forth .
Flowers
Whether annuals , biennial or perennials , flowers are a democratic option for landscape painting bed , molding plantings or patio lot . Flowers , whether raving mad flowers , cut flowers or 1 growing in your garden , are an example of evolution and , in many case , mankind ’s attempts to improve on nature . All flowering plants are vascular plant .
Herbs and Vegetables
Plants coalesce water , carbon copy dioxide and the sunshine ’s energy along with a little morsel of N , phosphorous and atomic number 19 to make food for themselves . Some plants are experts at manufacture supererogatory food and hive away it . People school these plant for food . The fruits , seeds , stalks , parting and tubers of many plants give people a variety of intellectual nourishment to enjoy and nourish themselves . The phylogeny of vascular plants includes the numerous herbs and veggie people grow for food and other uses .
