Pteridophytes are the only non-flowering seedless plants having vascular tissues. Modern seedless vascular plants include species from several different phyla, including the club mosses, spike mosses, and quill worts of the phylum Lycophyta, the horsetails of the phylum Sphenophyta, the whisk ferns of the phylum Psilotophyta, and the great diversity of ferns in the phylum Pterophyta. Note: A diploid sporophyte with a haploid gametophyte alternates the life-cycle of seedless vascular plants. The non-vascular plants are seedless although some vascular plants are also seedless for instance lycophytes and pterophytes. The ferns and horsetails belong to pteridophytes. CHARACTERISTICS • Pteridophytes derived from Greek words, pteron "feather" + phyton "plants". The plant body of these organisms has true roots, stems, and leaves: The plant body is divided into the stem, roots, and leaves. b. they share a more recent common ancestor with seeded plants than they do with the non-vascular plants. The pteridophytes . Further, they were the first plants to acquire vascular tissue namely xylem and phloem, hence called vascular . Charophyceans are the green algae most closely related to land plants. Haeckel (1866) called these groups of plants as "Pteridophytes" because of their pinnate or feather like fronds (leaves). 1. watching.

Pteridophytes are vascular plants and have leaves (known as fronds), roots and sometimes true stems, and tree ferns have full trunks. Another common characteristic of this group is that the diploid sporophyte is the most prominent phase of the life cycle. Besides being a lower plant, pteridophytes are economically very important. The ferns, gymnosperms, and flowering plants are all vascular plants. Add to Wishlist.

This is a sizable number, but these relatively unusual plants still represent less than five percent of all known living vascular plants. This plant group evolved by the late Devonian period and was the prominent group during the Carboniferous period of the Paleozoic era. They are the earliest known vascular plants which originated in the Silurian period (400 million years ago) of Palaeozoic Era and subsequently diversified and formed the dominant vegetation on earth during Devonian to Permian period. Pteridophytes are a diverse paraphyletic group of seedless, vascular plants that have an alternation of generations between a sporophyte and a gametophyte. The ferns and horsetails belong to pteridophytes. Explanation for incorrect answer: Option (a) Lycophytes and pterophytes are seedless vascular plants. The two major classifications of the plant kingdom are 1. So, the correct answer is option (b). o Xylem transports nutrients and water. Pteridophytes - ferns, horsetails, lycophytes a. Seedless plants b. Seedless vascular plants still depend on water during fertilization, as the sperm must swim on a layer of moisture to reach the egg. Hence, they are known as 'vascular cryptogams'. They breed on spores. Many well established compounds of medicinal uses are being extracted from these plants (Tables 1 and 2). Pteridophyta is one of the older groups of plants present in the Plant kingdom. •In vascular plants the branched sporophyte is dominant and is independent of the parent gametophyte. Although ferns and fern allies have vascular tissue, they exhibit a vastly different form of reproduction as other vascular plants, gymnosperms and angiosperms.Pteridophytes don't produce cones, flowers, or fruit, unlike these seed plants. The non-vascular plants are seedless although some vascular plants are also seedless for instance lycophytes and pterophytes. Bryophytes are distinct from other land plants (the "tracheophytes") because they do not contain xylem, the tissue used by vascular plants to transport water . • Ability to synthesize lignin (cell walls) . - sporophyte (diploid) has become larger and dominant. 3. One of the characteristics of pteridophytes . Characteristics of the four phyla of seedless vascular plants are summarized in Table 28-2. THE PHYLA OF SEEDLESS VASCULAR PLANTS 1. Their dominant phase of life cycle is represented by a gametophyte which is either leafy ( mosses) or thalloid ( liverworts and h. Wood, which is made up primarily of xylem, and bark, which contains phloem, are the major structural elements of the trunks and stems.These trees produce seeds, whether they be formed within the cones of the pines or within fruits, such as the winged samaras of maples or . Seedless Vascular Plants. They have 4 sub-divisions: (i) Psilopsida (Psilopsids) (ii) Lycopsida (Clubmosses), (iii) Sphenopsida (Horsetails) and (iv) Pteropsida(Ferns . They are classified due to the presence of vascularity and their ability to produce seed and flower. Introduction of Plant Kingdom. An example of pteridophytes is the fern. They are the vascular plants (those having xylem and phloem tissues) that reproduce by releasing spores rather than seeds, and they include the highly diverse true ferns and other graceful, primarily forest-dwelling plants. Pteridophytes commonly known as Vascular Cryptogams, are the seedless vascular plants that evolved after bryophytes. In seedless vascular plants, the sporophyte became the dominant phase of the lifecycle. Pteridophyta is classified into four main classes namely, Psilophyta, Lycophyta, Arthrophyta, Filicophyta.

Bryophytes: Amphibians of Plant Kingdom. Plant Diversity TABLE 2: SEEDLESS VASCULAR PLANTS CONCEPT 5: Some seedless plants evolved vascular tissue Seedless Vascular Plants Plant Phylums: Lycophyta and Monilophyta (Ex: Selaginella and Lycopodium) Organisms from this division, commonly known as spike mosses, quillworts, and club mosses, represent transitional organisms that share some traits with the divisions already examined, but . Plants in division Spermatophyta are characterized by the presence of seeds and are called seed plants; whereas the plants in all the other three divisions lack the presence of seeds and are called seedless plants. Vascular tissues are present, but xylem vessels and phloem companion cells are absent. The answer is; Bryophytes are nonvascular plants, and pteridophytes are seedless vascular plants. 1. For instance, living land plant diversity is typically divided right into 4 significant teams in introductory biology or botany kind of courses: bryophytes (nonvascular plants), ferns and fern allies (also dubbed seedless vascular plants, free-sporing vascular plants, or pteridophytes), gymnosperms (naked-seeded plants), and also angiosperms . Ferns, horsetails (often treated as ferns), and lycophytes (clubmosses, spikemosses, and quillworts) are all pteridophytes. seedless vascular plants heap to gate this day, this can be your referred book. Vascular plants are plants that have food-transporting phloem and water-transporting xylem tissues. Seedless vascular plants still depend on water during fertilization, as the flagellated sperm must swim on a layer of moisture to reach the egg. The key difference between bryophytes and seedless vascular plants is that bryophytes are non-vascular plants, while seedless vascular plants are vascular plants that do not produce seeds.. Kingdom Plantae is the kingdom that consists of all plants on Earth. They have evolved much earlier than the angiosperms. They are lower plants as compared to vascular plants like pteridophytes ,gymnosperms and angiosperms. The Phylum Pteridophyta is the largest of the phyla with around 9000-10,000 species; Lycopodiophyta has only around 1200 species. The major groups include lycophytes (clubmosses, quillworts, and spikemosses), which has a long and fascinating fossil history, with some examples of ancient clubmosses growing up to 40 . • They are considered as the first true land plants that evolved after bryophytes. What is the oldest vascular plants? In seedless vascular . Pteridophytes are the most advanced seedless group - true leaves with branched veins - sporophyte is dominant. Match the characteristics below to either seedless or seed plants. considered to be only two extant phyla of seedless vascular plants: the Pteridophyta (including the whisk ferns, horsetails, and the true ferns) and the Lycopodiophyta (club mosses, quillworts, and spikemosses).
