What is the classification of fern plant?
Fern. Ferns are a group of about 20,000 species of plants (of which about 10,000 are living) in the division Pteridophyta. Unlike bryophytes, ferns have xylem and phloem, which makes them vascular plants.Most ferns belong to the Class Leptosporangiata (or Pteridopsida).

What are ferns classified as?
Carl Linnaeus (1753) originally recognized 15 genera of ferns and fern allies, classifying them in class Cryptogamia in two groups, Filices (e.g. Polypodium) and Musci (mosses). By 1806 this had increased to 38 genera, and has progressively increased since ( see Schuettpelz et al (2018) Figure 1 ). Ferns were traditionally classified in the class Filices, and later in a Division of the Plant Kingdom named Pteridophyta or Filicophyta. Pteridophyta is no longer recognised as a valid taxon because it is paraphyletic. The ferns are also referred to as Polypodiophyta or, when treated as a subdivision of Tracheophyta (vascular plants), Polypodiopsida, although this name sometimes only refers to leptosporangiate ferns. Traditionally, all of the spore producing vascular plants were informally denominated the pteridophytes, rendering the term synonymous with ferns and fern allies. This can be confusing because members of the division Pteridophyta were also denominated pteridophytes ( sensu stricto ).
What is a fern?
A fern ( Polypodiopsida or Polypodiophyta / ˌpɒliˌpɒdiˈɒfɪtə, - oʊfaɪtə /) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers.
What is the anatomy of a fern?
The anatomy of fern leaves can either be simple or highly divided. In tree ferns, the main stalk that connects the leaf to the stem (known as the stipe), often has multiple leaflets. The leafy structures that grow from the stipe are known as pinnae and are often again divided into smaller pinnules.
How tall is a fern?
These can reach up to 20 meters (66 ft) tall in a few species (e.g., Cyathea brownii on Norfolk Island and Cyathea medullaris in New Zealand ). Leaf: The green, photosynthetic part of the plant is technically a megaphyll and in ferns, it is often referred to as a frond.

Fern-like taxa ( Wattieza) first appear in the fossil record in the middle Devonian period, ca. 390 Mya. By the Triassic, the first evidence of ferns related to several modern families appeared. The great fern radiation occurred in the late Cretaceous, when many modern families of ferns first appeared.
What is the science of classification of ferns?
Classifying ferns. Taxonomy is the science of classification. Dr Patrick Brownsey explains how botanists use reproductive structures (sporangia), vegetative characters (rhizome and frond shape) and microscopic characters (spore size) to classify ferns.

How many species of ferns are there in New Zealand?
Scientists currently consider that New Zealand has approximately 230 species of fern in about 50 different genera. They are widely distributed throughout the country, including around 42 species that are found on all 3 main islands. These are ferns you may know and recognise. Their common names may be familiar to you ( silver fern, hen and chickens fern) or perhaps you know their Māori name (ponga, mouku).
What are the parts of a fern?
Dr Patrick Brownsey shows us the 3 major parts of a fern: the rhizome (the underground stem), the leafy frond and the sporangia (the reproductive structure).
What is the rhizome of a fern?
When classifying fern species, vegetative characters such as the rhizome become important. The rhizome is the stem of the fern plant. It can be creeping, vertical or erect.
What is the name of the fern that is white washed?
This orderly system gives each plant a ‘generic’ name (genus) and then a ‘specific’ name (species). In this system, the silver fern is known as Cyathea dealbata (the species name is descriptive meaning ‘white washed’), and the hen and chickens fern is known Asplenium bulbiferum (the species name is descriptive meaning ‘bearing bulbs’).
What are the reproductive structures of ferns?
The reproductive structures are the most important characteristic for classifying ferns. When you turn over a fern frond and look at the sporangia on the underside, you’ll quickly see that they are grouped together into various shapes and patterns.
What is a fern?
By definition, a fern is a vascular, flowerless plant with leafy fronds that produce spores for reproduction. Whether they add depth and dark green accents to your garden, spruce up a terrarium, or just remind you of scenes from Jurassic Park, ferns are truly remarkable plants.
How many different types of ferns are there?
Let’s jump into our 50+ different fern types. Read along to find the best fern for your home or garden.
What do fronds look like?
The fronds look, for the most part, like the quintessential fern leaf, and are twice-cut pinnately compound.
What happens after a fern grows?
After growing spores, they are released and the process begins again! Bulbets and fernlets are the exceptions to this cycle. Forms of asexual reproduction, these are ways that some ferns will produce clones of themselves that plant themselves and grow into individual plants. Fern Life Cycle, Fiddlehead example.

What Is a Fern?
A fern is a class of plants that reproduce via spores, not flowers nor seeds. While botanists are still bickering about the classification of these plants, most would agree that they belong to the Petridophytes division.
Where do ferns come from?
There are many types of ferns you can grow both outdoors and indoors; some come from tropical and subtropical regions, others even from cold areas of the world. This makes the range of leaf shapes and colors huge. Thus, if you are thinking about growing ferns and you are looking for some good ideas to choose the best fern varieties ...
Why do we put ferns on our desks?
Indoors, though, ferns are often used to bring a touch of “exotic permanence”. Because they look immutable, often being green and lush all year round, a fern on your desk or by your sofa will tend to bring a sense of peace matched only by the sculptural qualities of the fern itself you have chosen.
What does a delta shaped fern do?
This fairly small Fern variety will produce an abundance of fronds with a purple – black stalks and the leaves, delta shaped (the clue was in the name) will create a wonderful effect of dappled light and rich foliage.
Why is rabbit's foot fern called rabbit's foot fern?
Did I say that ferns actually have many more shapes than people think? Well, rabbit’s foot Fern is so called because it has fuzzy rhizomes that grow out of the soil and look like, of course, rabbit’s feet.

It tolerates clay soil and well as wet soil. 2. Hart’s Tongue Fern (Asplenium scolipendrium) If the exotic look of the foliage is what you are after, you can have it even in temperate zones with the amazing hart’s tongue fern varity. The leaves, in fact, are bright, light green, very glossy and exotic looking.
Why is the fern called Grey Ghost?
Just to prove my point that there’s a lot of variety with ferns, how about a silvery white one? This cultivar is called ‘Grey Ghost’ because the shade of the leaves is just surreal .
What are the two types of ferns?
Ferns come in two major types: the eusporangiate ferns and the leptosporangiate ferns. Eusporangiate fern spores arise from several epidermal cells, called sporangia. These plants tend to have relatively small root systems and produce large numbers of spores.
What is the division of ferns called?
However, modern taxonomy places the ferns in their own phylum or division. This division is called the Pteridophyta. It may also be referred to as the Filicophyta or the Polypodiophyta. When this phylum is treated as a subdivision of the Tracheophyta, or vascular plants, it may be referred to as the Polypodiopsida.
What are the four main phylums of ferns?
The fern phylum contains four main orders: the Polypodiales, Hydropteridales, Marattiales and Ophioglossales. The Marattialies contains only vessel ferns, while the Ophioglossales, or snake-tongue ferns, contain the adders tongues, grape ferns and moonworts.

What are fern allies?
Fern allies are plants that closely resemble true ferns, but do not share all the same characteristics. This group includes the clubmosses and their relatives, horsetails and scouring-rushes, and whisk ferns. Fern allies also reproduce via spores, but may not have leaves the way ferns do.
Do ferns have flowers?
●. 21 September, 2017. Jupiterimages/Photos.com/Getty Images. Ferns are vascular plants, containing both phloem and xylem, and have roots, stems and leaves as do most other types of plants. However, unlike trees, flowering shrubs and most other plant types, ferns do not produce flowers or seeds.
Is fern a phyla?
Plants, including ferns, are normally classified in divisions, rather than in phyla. However, divisions occupy the same taxonomical place and function as phyla.

Staghorn Fern. As the name suggests, the fronds of this variety resemble the antlers of a stag. Reasonably easy to take care of as long as you make sure not to overwater, as it is susceptible to root rot. Ideally grown in humus-rich coarse soils with excellent drainage.
What are the parts of a fern called?
To understand fern reproduction, it helps to know the parts of fern. Fronds are the leafy "branches," consisting of leaflets called pinnae. On the underside of some pinnae are spots that contain spores. Not all fronds and pinnae have spores. Fronds that do have them are called fertile fronds .
How many generations does a fern have?
Ferns alternate generations as part of their life cycle. The fern life cycle requires two generations of plants to complete itself. This is called alternation of generations . One generation is diploid, meaning it carries two identical sets of chromosomes in each cell or the full genetic complement (like a human cell).
How do ferns grow?
Starting with the "fern" as we recognize it (the sporophyte), the life cycle follows these steps: 1 The diploid sporophyte produces haploid spores by meiosis, the same process that produces eggs and sperm in animals and flowering plants. 2 Each spore grows into a photosynthetic prothallus (gametophyte) via mitosis. Because mitosis maintains the number of chromosomes, each cell in the prothallus is haploid. This plantlet is much smaller than sporophyte fern. 3 Each prothallus produces gametes via mitosis. Meiosis is not needed because the cells are already haploid. Often, a prothallus produces both sperm and eggs on the same plantlet. While the sporophyte consisted of fronds and rhizomes, the gametophyte has leaflets and rhizoids. Within the gametophyte, sperm is produced within a structure called an antheridium. The egg is produced within a similar structure called an archegonium. 4 When water is present, sperm use their flagella to swim to an egg and fertilize it. 5 The fertilized egg remains attached to the prothallus. The egg is a diploid zygote formed by the combination of DNA from the egg and sperm. The zygote grows via mitosis into the diploid sporophyte, completing the life cycle.

Why do ferns droop?
As the baby fern grows, its weight causes the frond to droop toward the ground. Once the baby fern roots itself, it can survive separate from the parent plant. The proliferous baby plant is genetically identical to its parent. Ferns use this as a method of quick reproduction.
What are spores in ferns?
Spores are tiny structures that contain the genetic material needed to grow a new fern. They may be green, yellow, black, brown, orange, or red. Spores are encased in structures called sporangia, which sometimes clump together to form a sorus (plural sori). In some ferns, sporangia are protected by membranes called indusia. In other ferns, the sporangia are exposed to air.
How is a fertilized egg formed?
The fertilized egg remains attached to the prothallus. The egg is a diploid zygote formed by the combination of DNA from the egg and sperm. The zygote grows via mitosis into the diploid sporophyte, completing the life cycle. Before scientists understood genetics, fern reproduction was mystifying.

Description
Extant ferns are herbaceous perennials and most lack woody growth. Their foliage may be deciduous or evergreen, and some are semi-evergreen depending on the climate. Like the sporophytes of seed plants, those of ferns consist of stems, leaves and roots. Ferns differ from seed plants in reproducing by spores. However, they also differ from spore-producing bryophytes in that, like seed pla…
Distribution and habitat
Ferns are widespread in their distribution, with the greatest richness in the tropics, and least in arctic areas. The greatest diversity occurs in tropical rainforests. New Zealand, for which the fern is a symbol, has about 230 species, distributed throughout the country.
Ecology
Fern species live in a wide variety of habitats, from remote mountain elevations, to dry desert rock faces, bodies of water or open fields. Ferns in general may be thought of as largely being specialists in marginal habitats, often succeeding in places where various environmental factors limit the success of flowering plants. Some ferns are among the world's most serious weed species, including the b…
Uses
Ferns are not as important economically as seed plants, but have considerable importance in some societies. Some ferns are used for food, including the fiddleheads of Pteridium aquilinum (bracken), Matteuccia struthiopteris (ostrich fern), and Osmundastrum cinnamomeum (cinnamon fern). Diplazium esculentum is also used in the tropics (for example in budu pakis, a traditional dish of Brunei ) as food. Tubers from the "para", Ptisana salicina (king fern) are a traditional food in New …
Culture
The study of ferns and other pteridophytes is called pteridology. A pteridologist is a specialist in the study of pteridophytes in a broader sense that includes the more distantly related lycophytes.
Pteridomania is a term for the Victorian era craze of fern collecting and fern motifs in decorative art including pottery, glass, metals, textiles, wood, printed paper, and
Organisms confused with ferns
Several non-fern plants (and even animals) are called ferns and are sometimes confused with ferns. These include:
• Asparagus fern—This may apply to one of several species of the monocot genus Asparagus, which are flowering plants.
