Soral evolution in pteridophytes pdf
This event is a precursor to the seed habit considered an important step in evolution. The term Pteridophyta was first introduced by Haeckel in 1866. The term Cryptogams was coined by Linnaeus (1737) which means plants without seeds. Tracheophytes : Sinnott (1935) coined the term to include vascular plants (pteridophytes and seed plants). The chloroplasts of Selaginella contain pyrenoids. …

A new fern species, Leptochilus oblongus of Polypodiaceae is described and illustrated from Hoa Binh Province, northern Vietnam. Leptochilus oblongus is most similar to L. ellipticus, but the sori of the former are oblong, close to the lobe margins, and parallel with costule.
4/09/2013 · Here we discuss the theories of leaf evolution in ferns, morphology, and diversity of fern leaves, and experimental results of fern leaf development. We summarize what is known about the molecular genetics of fern leaf development and what future studies might tell us about the evolution of fern leaf development.
Evolution is the result of a suite of incessant attempts to improve fitness and take advantage of opportunities, such as escaping competition and occupying a new habitat.
In further studies of soral morphogenesis in common British ferns, consideration is given to environmental and other factors which may be causally involved. Accounts are given of the normal course of sporophyll development in Dryopteris austriaca and of the effects of more or less extensive defoliation on the inception of sori in several ferns.
As the distal part enlarges to form the sporocarp two rows of soral mother cells appear on the ventral side, arising directly from the marginal cells of the earlier stage. Later the marginal cell and their derivatives are pushed downwards to the lower surface and slightly towards the median line due to unequal growth of the cells.
Geological concept of Fossil Pteridophytes, different types and their distribution 03 Criteria and comparative systems of Classification of Pteridophytes 03 Cytological evolution of fern flora and their taxonomical significance.
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.
A sorus (pl. sori) is a cluster of sporangia (structures producing and containing spores) in ferns and fungi. This New Latin word is from Ancient Greek σωρός (sōrós ‘stack, pile, heap’).
A. Pteridophytes provide clues to evolution of roots and leaves 1. There is evidence that roots evolved from subterranean portions of stems. 2. There are two types of leaves: a. Leaves of lycophytes are microphylls. Microphylls are small leaves with a single, unbranched vein. b. Leaves of other modern vascular plants are megaphylls. Megaphylls are typically larger and have a branched vascular
Pteridophytes may represent the closest living relatives (sister group) to the seed plants. (Seed plants include the angiosperms, the conifers, and a smaller assortment of other plants.) (Seed plants include the angiosperms, the conifers, and a smaller assortment of other plants.)

A. Pteridophytes provide clues to evolution of roots and leaves 1. There is evidence that roots evolved from subterranean portions of stems. 2. There are two types of leaves: a. Leaves of lycophytes are microphylls. Microphylls are small leaves with a single, unbranched vein. b. Leaves of other modern vascular plants are megaphylls. Megaphylls are typically larger and have a branched vascular

10/04/2006 · Best Answer: Another way you can look at sorus evolution is to consider the sporangia. The more primitive ferns are called eusporangiate ferns and their sori are made up of a clump of simple sporangia that release their spores by opening up a pore or slit (see first pic).

In further studies of soral morphogenesis in common British ferns, consideration is given to environmental and other factors which may be causally involved. Accounts are given of the normal course of sporophyll development in Dryopteris austriaca and of the effects of more or less extensive defoliation on the inception of sori in several ferns.
