Lycophytes Dataset English Wikipedia - Species Pages Classification Abstract The lycophytes, when broadly circumscribed, what is the dominant generation in gymnosperms a vascular plant tracheophyte subgroup of the kingdom Plantae. They are sometimes placed in a division Lycopodiophyta or Lycophyta or in a subdivision Lycopodiophytina.

They what is the dominant generation in gymnosperms one of the oldest lineages of extant living vascular plants; the group contains extinct plants that have been dated from the Silurian ca. Lycophytes were some of the dominating plant species of the Carboniferous period, geheration included tree-like species, although extant lycophytes are relatively small plants. The scientific names and the informal English names used for this group of plants are ambiguous. For example, "Lycopodiophyta" and the shorter "Lycophyta" as well as the informal "lycophyte" may be used to include the extinct zosterophylls or to exclude them.

Lycophytes reproduce by spores and have alternation of generations in which like other vascular plants the sporophyte generation is dominant. Some lycophytes are homosporous while others are heterosporous. Eichhorn, Evert, and Raven Biology of Plants, Seventh Edition. When broadly circumscribed, the lycophytes represent a line of evolution distinct from that leading to all other vascular plants, the euphyllophytes, such as ferns, gymnosperms and flowering plants.

They are defined by two synapomorphies: lateral rather than terminal sporangia often kidney-shaped or reniformand exarch protosteles, in which the protoxylem is outside the metaxylem rather than vice versa. The extinct zosterophylls have at most only flap-like extensions of the stem "enations" rather than leaves, whereas extant lycophyte species have microphylls, leaves that have only a single vascular trace veinrather than the much domminant complex megaphylls of other vascular plants.

The extinct genus Asteroxylon represents a transition between these two groups: it has a vascular trace leaving the central protostele, but whhat extends only to the base of the enation. Zosterophylls and extant lycophytes are all relatively small plants, but some extinct species, such as the Lepidodendrales, were tree-like, and formed extensive forests that dominated the what is the dominant generation in gymnosperms and contributed to the formation of coal.

Suggested evolution of microphylls: 1 Sawdonia 2 Asteroxylon 3 Leclercqia Within the broadly defined lycophyte group, species placed in the class Lycopodiopsida are distinguished from species placed in the Zosterophyllopsida by the possession of microphylls. Some zosterophylls, such as the What is the dominant generation in gymnosperms Zosterophyllum myretonianum, had smooth stems causal relationship research methods. Others, such as Sawdonia ornata, had flap-like extensions on the stems "enations"but without any vascular tissue.

Asteroxylon, identified as an early lycopodiopsid, had vascular traces that extended to the base of the enations. Species in the genus Leclercqia had fully vascularized microphylls. These are considered to be stages in the evolution of microphylls. File:Lycopod bark. File:Lycopsid joggins mcr1.

Classification In ahat broadest circumscription of the lycophytes, the group includes the extinct zosterophylls as well as the extant living lycophytes and their closest extinct relatives. The names and ranks gneration for this group vary considerably. Some whzt use the names "Lycopodiophyta" or the shorter "Lycophyta" to include zosterophylls as well as extant lycophytes and their closest extinct relatives, while others use these names to exclude zosterophylls.

The name "Lycopodiophytina" has also been used in the inclusive sense. English names, such as "lycophyte", "lycopodiophyte" or "lycopod", are similarly ambiguous, and may refer to the broadly defined group or only to the extant lycophytes and their closest extinct relatives. The consensus classification produced by the Pteridophyte Phylogeny Group classification in PPG I places all extant living lycophytes in the class Lycopodiopsida.

There are around 1, to 1, such species. For more information on the classification of extant lycophytes, see. Phylogeny A major cladistic study of land plants was published in by Kenrick and Crane. InCrane et al. Their cladogram for the lycophytes physical relationship between husband and wife in islam reproduced why does my wifi say cannot verify server identity with some branches collapsed into 'basal groups' to reduce the size of the diagram.

In this view, the "zosterophylls" comprise a paraphyletic group, ranging from forms like Hicklingia, which had bare stems, to forms like Sawdonia and Nothia, whose stems are covered with unvascularized spines or enations. The genus Renalia illustrates the problems in classifying early land plants. It has characteristics both of the non-lycophyte rhyniophytes — terminal rather than lateral sporangia — and of the zosterophylls — kidney-shaped sporangia opening along the distal margin.

A rather different view is presented in a analysis by Hao and Xue. Their preferred cladogram shows the zosterophylls and associated genera basal to both the lycopodiopsids domibant the euphyllophytes, so that there is no clade corresponding to the broadly defined group of lycophytes used by other authors. Some extinct orders of lycophytes fall what is the dominant generation in gymnosperms the same group as the extant orders.

Different sources use varying numbers and names of the extinct orders. The following phylogram shows a likely relationship between some of gy,nosperms proposed Lycopodiopsida orders.
