What are rhizomes in ferns?
The stem of a fern is referred to as the rhizome. A fern can be thought of as an erect plant that is laying on its side. The rhizome develops horizontally beneath the surface of the soil. Some rhizomes elevate closer to the surface level of the ground at the tip.
Do ferns have stems?
Ferns generally reproduce by producing spores. Similar to flowering plants, ferns have roots, stems and leaves. However, unlike flowering plants, ferns do not have flowers or seeds; instead, they usually reproduce sexually by tiny spores or sometimes can reproduce vegetatively, as exemplified by the walking fern.

Is a fern a Pteridophyte?
The Pteridophytes (Ferns and fern allies) Pteridophytes are vascular plants and have leaves (known as fronds), roots and sometimes true stems, and tree ferns have full trunks. Examples include ferns, horsetails and club-mosses. Fronds in the largest species of ferns can reach some six metres in length!
Why are fern stems inconspicuous?
Fern stems (rhizomes) are often inconspicuous because they generally grow below the surface of the substrate in which the fern is growing. This substrate can be soil, moss or duff. People often confuse rhizomes with roots. Fern roots are generally thin and wiry in texture and grow along the stem.

What are dimorphic ferns?
Some ferns have two kinds of fronds: fertile fronds (leaves with sporangia) and sterile fronds (leaves lacking sporangia). Ferns with two kinds of leaves are referred to as dimorphic. Examples of dimorphic ferns are deer fern ( Blechnum spicant) and cinnamon fern ( Osmunda cinnamomea ). Deer fern ( Blechnum spicant ).
What do ferns absorb?
They absorb water and nutrients and help secure the fern to its substrate. Stems can be short-creeping with fronds that are somewhat scattered along the stem, such as the fragile fern; or, stems can be long-creeping resulting in fronds scattered along the stem, exemplified by the licorice fern.

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 ).

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.
How to tell if a plant is a fern?
Another way to tell if a plant is a fern is to look at its reproductive structures. If it has a flower, fruit, or seed- it’s not a fern! All ferns, and many fern relatives, reproduce using spores, or tiny living single cells. Typically, reproductive fronds will produce sori, or spore dots on the undersides of their leaflets. Within these sori, hundreds of thousands of spores are developed in little packets known as sporangia, and released when mature.
What is the group of plants that are similar to ferns?
Largely due to having a similar appearance and way of reproducing themselves, a group called the “fern allies” is classified with the ferns.

Why are fern leaves called fiddleheads?
Young fronds, called fiddleheads because of their striking resemblance to the head of a violin, start out tightly curled at the base of the root. They then slowly unroll themselves much like a scroll unrolls as they grow. This special way of growing is a response to light. The cells in the fiddlehead that are exposed to light will get bigger and grow, causing the frond to lengthen and unfurl.
Where do fern roots grow?
Both fern fronds and roots grow directly from the stem, which is also known as the rhizome. All new growth is produced at the stem tip, and if it is damaged the entire plant may be killed. The roots grow at the base of the fronds, or on the lower side of creeping rhizomes. In all ferns they are close to the surface and easily disturbed.

Overview
A fern is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, …
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…
