Fern A fern is a member of a group of approximately 12,000 species of vascular plants that reproduce via spores and have neither seeds nor flowers.They differ from mosses by being vascular (i.e. having water-conducting vessels). They have stems and leaves, like other vascular plants.he gametophytes of ferns, however, are very different from those of seed plants. Instead, they resemble liverworts. A fern gametophyte typically consists of: 1  Prothallus: A green, photosynthetic structure that is one cell thick, usually heart or kidney shaped, 3–10 mm long and 2–8 mm broad.

- There may be up to 12,000 types of ferns. Ferns are known as vascular plants. They do not have seeds or flowers as they reproduce via spores. Ferns are generally known in horticulture as landscape plants. They are also used as houseplants and cut foliage. Cut ferns are especially useful in floral arrangements.

Different Types of Ferns The roughly 20,000 species of this seedless and flowerless plant reproduce via spores, which develop on its fertile fronds. In the landscape, gardeners frequently plant ferns as edging and to add texture. Some types do well in containers, and most resist rabbits and deer.

- Ferns, horsetails, and their allies make up the second group of land plants, the pteridophytes. These plants all have vascular systems, made up of xylem (flow of water and nutrients from roots to leaves) and phloem (flow of sugars and other metabolic products from leaves to roots). Mosses do not have vascular systems. Ferns, however, do not have flowers.

- Most ferns are small plants that lack woody tissue. In this lab you will investigate the diversity of pterophytes, including whisk fens, horsetails and a variety of ferns. The plants on display are sporophytes, the dominant generation in seedless vascular plants.Procedure: 1. Examine a living whisk fern on display. This is one of only two extant genera of Psilophytes. Observe the spherical structures on the stem.n this lab you will investigate the diversity of pterophytes, including whisk fens, horsetails and a variety of ferns.

What Are Fern Leaves Called? Fern leaves grow from a rhizome. Fern leaves are fan-shaped and also play an important role in reproduction. The production of spores occurs in structures called sporangia. These structures are found on the surface of the fronds, usually on the underside of the leaf. When the sporangia or spore casings dry out, the dispersal of spores occurs into the atmosphere. Certain fern species date back nearly 400 million years. There are about 12,000 fern species.

Cyatheales The fronds of tree ferns are usually very large and multiple-pinnated, but at least one type has entire (undivided) fronds. The fronds of tree ferns also exhibit circinate vernation, meaning the young fronds emerge in coils that uncurl as they grow.he order Cyatheales, which includes the tree ferns, is a taxonomic division of the fern class, Polypodiopsida.

They have stems and leaves, like other vascular plants.ost ferns have what are called fiddleheads that expand into fronds, which are each delicately divided. Leptosporangiate ferns (sometimes called true ferns) are by far the largest group, but ferns as defined here (ferns sensu lato) include horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns.

- The Embryophyta are the most familiar group of green plants that form vegetation on earth. Living embryophytes include hornworts, liverworts, mosses, ferns, lycophytes, gymnosperms and flowering plants, and emerged within the Charophyte green algae. The Embryophyta are informally called land plants because they live primarily in terrestrial habitats, while the related green algae are primarily aquatic.

Fern fern. 1  any of several nonflowering vascular plants that possess true roots, stems, and complex leaves and that reproduce by spores.

What is Moss? Adorable animal families that will make you aww. Moss is a very simple type of plant that lacks conventional roots, stems, and leaves. The name refers to any species of the class Bryopsida and is part of the division Bryophyta. Bryophyta means the first green land plants to develop during the evolutionary process.

- Although most ferns reproduce using spores, one group evolved seeds although they were not ancestral to other seed plants. Fern leaves possess a highly branched vascular system. Some ferns in. have leaves that are 6-9 m long and probably the most complex leaves in the plant kingdom.nlike most algae, land plants have a multicellular jacket for protecting the reproductive cells. BRYOPHYTES: liverworts, hornworts, mosses; 23,000 modern species. Spores of bryophytic plants represent the first known land plants from the Middle Ordovician.

- About the Sporophyte Stage. Ferns in the sporophyte stage have spore-bearing fronds called sporophylls that produce clusters of sporangia on their undersides. These contain cells that become spore mother cells, and each of these splits into meiospores.The sporangia erupt when they mature, shooting dust-like spores into the air.erns in the sporophyte stage have spore-bearing fronds called sporophylls that produce clusters of sporangia on their undersides.

- Ferns. The first plants that had leaves evolved from plants that were more like moss about 360 million years ago. We call these early plants with leaves ferns. Like moss, most ferns grow in places where there is plenty of water: usually near the banks of streams.But eventually some ferns were able to figure out how to live in dry places too. Many ferns had underground stems, like mushrooms.e call these early plants with leaves ferns. Like moss, most ferns grow in places where there is plenty of water: usually near the banks of streams.

More About Ferns (monilophytes) Some past authorities had lumped them in with other non-seed bearing vascular plants such as lycopsids (club mosses, spike mosses and quillworts), sphenophytes (horsetails) and psilophytes (whisk ferns); the common phrase ferns and fern allies is a legacy of this classification scheme.

Ferns Ferns don't have seeds, they have spores. The spores are usually on the underside of the fronds. To reproduce, the fern releases the spores into the air. The spores don't grow into new ferns. They grow into something called a prothallus.

- Fern Sporophyte. Fern is a common name for the cryptogamous (spore-producing) plants belonging to the division Filicophyta, also called Filicinophyta or Pterophyta of seedless vascular plants. They are primitive vascular plants with true roots, stems, and complex leaves.

More About Ferns (monilophytes) The fossil record is meager, with the earliest record occurring in the Paleocene of Canada. Two of the remaining extant fern groups, sphenopsids (horsetails; also known as equisetopsids) marattioid ferns may be more closely related to each other than they are to the third group, leptosporangiate ferns.

Vascular plant Vascular plants (from Latin vasculum: duct), also known as tracheophytes (from the equivalent Greek term trachea) and also higher plants, form a large group of plants that are defined as those land plants that have lignified tissues (the xylem) for conducting water and minerals throughout the plant.ascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers) and angiosperms (flowering plants). Scientific names for the group include Tracheophyta and Tracheobionta.

Moss Botanically, mosses are non-vascular plants in the land plant division Bryophyta. They are small (a few centimeters tall) herbaceous (non-woody) plants that absorb water and nutrients mainly through their leaves and harvest carbon dioxide and sunlight to create food by photosynthesis.ichens may superficially look like mosses, and have a common names that includes the word moss (e.g.,  reindeer moss  or  iceland moss ), but are not related to mosses. Mosses, hornworts, and liverworts are collectively called  bryophytes .

Lady fern Lady Fern are speciess of deciduous, perennial ferns with the scientific name belonging to the genus Athyrium. Its name is derived from its reproductive structures which are found on the sides of the frond (the leaf of the fern) and hidden in a way deemed female. Another name by which it is known is the Wood Ferns Wife.
