The Reproductive Parts of Plants Spores and Sporangium. Ferns differ from flowering plants and trees because they do not produce seeds. Instead, ferns reproduce using spores. The sporangium is the structure responsible for producing and releasing spores. Sporangium form in many different ways, sometimes appearing as brown fruitdots on the undersides of leaves. Others grow as slender stalks up from the plant. When the sporangia burst, the wind carries spores to new ground, where they form reproductive structures that, if fertilized, will grow into a new fern.

- In ferns and most flowering plants, the mesophyll is divided into two layers: 1  An upper palisade layer of vertically elongated cells, one to two cells thick, directly beneath the adaxial epidermis, with intercellular air spaces between them. 2  Beneath the palisade layer is the spongy layer.

- Unlike 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.Bryophytic and vascular plants are found together in an Early Devonian hot spring environment (Park, 2007).lthough 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.

What Is The Frond Of A Fern? Fern fronds are the leaves of ferns and are a major organ of a fern. Some fronds can be longer than 5 m while others are less than 1 cm in length. Fern fronds are the leaves of ferns and are a major organ of a fern.

How to Grow Ferns From Spores The mature fern is referred to as a sporophyte. The sporophyte produces sporangia (spores) through meiosis. The sporangia are found in clusters called sori under the leaves of most ferns.

- First, all plants undergo an alternation of generations, between a haploid gametophyte stage and a diploid sporophyte stage. In the most primitive plants, like mosses, the gametophyte is dominant (i.e. it's big and green).In higher plants like ferns and fern allies, the sporophyte stage is dominant.osses and liverworts are lumped together as bryophytes, plants lacking true vascular tissues, and sharing a number of other primitive traits. They also lack true stems, roots, or leaves, though they have cells that perform these general functions.

Sporangium Equisetum arvense strobilus cut open to reveal sporangia. A sporangium (pl., sporangia) (modern Latin, from Greek σπόρος (sporos) ‘spore’ + αγγείον (angeion) ‘vessel’) is an enclosure in which spores are formed. It can be composed of a single cell or can be multicellular.ori may be covered by a structure called an indusium. Some ferns have their sporangia scattered along reduced leaf segments or along (or just in from) the margin of the leaf. Lycophytes, in contrast, bear their sporangia on adaxial surface (the upper side) of leaves or laterally on stems.

Fern A fern is a leafy vascular plant that does not flower. Its leaves are called fronds, and it reproduces with the help of spores.There are many varieties of fern, around 12,000 species, making it the largest family of plants. Ferns are versatile plants; they grow in a variety of conditions all over the world, though most of them need a lot of moisture to survive.Ferns have been around for centuries with some fossils indicating up to 360 million years ago.ts leaves are called fronds, and it reproduces with the help of spores.

GAMETOPHYTE DEVELOPMENT IN FERNS While the functions of the gametophyte (to produce gametes) and sporophyte (to produce spores) are also different, recent studies reviewed here indicate that the gametophyte responds to the environment using mechanisms similar to those used by the more complex sporophytes of angiosperms.

moss & fern notes b1 Fern Life Cycle: Spores produced on underside of fronds in clusters of sporangia called sori. Spores undergo meiosis, are spread by wind, & germinate on moist soil to form prothallus. Prothallus begins the Gametophyte stage. Mature Gametophytes are small, heart-shaped structures that live only a short time.

Growing ferns from spores The fern life cycle. Ferns do not flower but reproduce sexually from spores. There are two distinct stages of the fern life cycle. Mature plants produce spores on the underside of the leaves. When these germinate they grow into small heart-shaped plants known as prothalli.Male and female cells are produced on these plants and after fertilisation occurs the adult fern begins to develop.ature plants produce spores on the underside of the leaves.

Fern Fern, any of several nonflowering vascular plants that possess true roots, stems, and complex leaves and that reproduce by spores. They belong to the lower vascular plant division Pteridophyta, having leaves usually with branching vein systems; the young leaves usually unroll from a tight fiddlehead, or crozier.

Basic Fern Identification Some ferns species produce mostly sterile fronds (without sori), while also producing one or more fertile fronds (with sori). Other ferns consist entirely of fertile fronds. And in some fern species, the sori only emerge from some of the pinnae, while they are absent from the rest of the pinnae. Examining the stalk of a frond can also be a help in identifying the fern species. The part of the stalk from the ground to the beginning of the frond’s leafy area is known as the stipe.

- 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.

- The above-ground part of the plant is called a frond or leaf, and is divided into two major parts, a leafless stem called a stipe that reaches from the rhizome to the other and much larger part, the blade (Jones, 1987; Mickel, 1979).he sporangium contains the spores until they are ripe. When this time comes, a ring of cells around the sporangium called an annulus bursts open, causing the sporangium to snap open, casting the spores upon the wind (Frankel, 1981). The spores eventually land, but they do not produce a recognizable fern.

- For the seedless vascular plants, the sporophyte stage is the longest part of the cycle, but the cycle is similar to nonvascular plants. For example, in ferns, the gametophyte is a tiny heart-shaped structure, while the leafy plant we recognize as a fern is the sporophyte (see Figure above).ike all plants, nonvascular plants have an alternation of generations life cycle. In the life cycle of the nonvascular seedless plants, the gametophyte stage is the longest part of the cycle. The gametophyte is photosynthetic.

The moss sporophyte depends on the gametophyte and is not a free‐living independent plant. The spores form after meiosis and germinate to develop into male or female gametophytes.Moss sperm are produced from cells in the antheridia of the male gametophyte.The moss eggs are located at the base of the archegonia, on the female gametophyte. Each sperm has two flagella. Sperm swim to the eggs and after fertilization, the zygote develops into the sporophyte.oss sperm are produced from cells in the antheridia of the male gametophyte.

Frond Unfurling fiddlehead fern frond. A frond is a large, divided leaf. In both common usage and botanical nomenclature, the leaves of ferns are referred to as fronds and some botanists restrict the term to this group. Other botanists allow the term frond to also apply to the large leaves of cycads and palms (Arecaceae).

- As you recorded in question 3, an important feature of plants is alternation of generations. It is time now to learn how this process works, and a study of the moss life cycle is a good place to begin. Label the following features: male gametophyte, antheridia, female gametophyte, archegonia, egg, zygote, and sporophyte.
