Most of the plants on Earth — over 80% — are angiosperms (the rest are a mixture of gymnosperms, bryophytes, and seedless vascular plants (ferns)). View Video Only Save Timeline Video Quiz Course 487K views Characteristics of Angiosperms Angiosperm Anatomy Angiosperms have several ...
Another essential characteristic of vascular plants is that the principal generation phase in these plants is the sporophytic phase where they produce diploid spores. Vascular plants are tall and large in size compared to the non-vascular plants because of their ability to transport necessary substance...
Phloem, tissues in plants that conduct foods made in the leaves to all other parts of the plant. Phloem is composed of various specialized cells called sieve elements, companion cells, phloem fibers, and phloem parenchyma cells. Primary phloem is formed
Fruit, the fleshy or dry ripened ovary of a flowering plant, enclosing the seed or seeds. The principal purpose of the fruit is the protection and dispersal of the seed, though some seedless fruits have been developed. Learn more about the definition of

and angisperm dicots.Fernsare seedless, vascular plants that spread by roots, cuttings, or spores, among other ways. Plants under the categories of gnetophytes, moonwarts, brakes, ginkos, and cycads usually get grouped under ferns due to their "unevolved" and simple characteristics.Gymnosperms...
Saprophagous: (of certain animals) feeding on dead or decaying animal matter; saprozoic; herbivorous. Saprophytic: (of some plants or fungi) feeding on dead or decaying organic matter; herbivorous. –The much more rapid spread of the hyphae up into the parts thus killed sufficiently indicates ...
This phylum consists of over 12,000 species and over two thirds of them are tropical and consist of species of ferns and fern allies. Pteridophytes are seedless plants. They reproduce using spores on the underside of their leaves. These are known as sporophylls. They do not flower or hav...
Vascular plant, any of some 260,000 species of plants with vascular systems, including all of the conspicuous flora of Earth today. The vascular system consists of xylem, concerned mainly with the conduction of water and dissolved minerals, and phloem, w
Plant reproductive system, any of the systems, sexual or asexual, by which plants reproduce. Asexual reproduction results in offspring that are identical to the parent plant. Sexual reproduction involves new genetic combinations and results in offspring
