Various animals use the fronds as food while birds and small creatures use the plants for cover. Bryophyta and Pteridophyta. Introduction (eds) Pteridophytes and Gymnosperms. In: Kramer K.U., Green P.S. Pteridophytes are vascular cryptogams. The life cycle of pteridophytes is a continuous reproductive process that is dominated by the sporophyte (sexual) stage of the alternation of generations. ... Green P.S. Introduction. Pteridophytes are the first evolved plant group with a vascular tissue system for the conduction of water and food materials. They are called the "Reptiles of the plant Kingdom". Introduction A fern, or Pteridophyte, is any one of a group of plants classified in the Division Pteridophyta, formerly known as Filicophyta.Ferns are seedless vascular plants and reproduces by spores and by alternating generations of separate spore producing plants (sporophytes) and gamete producing plants (gametophytes). Compare and contrast the properties of Pteridophytes from other plants. An Introduction to the Pteridophytes of Hainan Island, South China. image1711. Lycopodiopsida, or lycophytes have at least four genera and more than 1,200 species.Lycophytes belong to microphyllous lineage of pteridohytes. Pteridophytes may represent the closest living relatives (sister group) to the seed plants. As they produce neither flowers nor seeds, they are referred to as Cryptogams. They occupy the position between bryophytes and Spermatophytes. CHAPTER 17: Pteridophytes structure and reproduction . The pteridophytes of Luxembourg. Introduction. Pteridophytes show diplohaplontic life cycle. Friends you can help me in my life journey through out the paytm my paytm number is 9027282381 In addition, in pteridophytes, the gametophyte is often very thin and can be unistratose, especially at the margins (Yatskievych, 2003). These pteridophytes are indispensably integral parts of forests world over. Even today, many tribal communities and rural populations are dependent heavily upon the natural resources obtained from the surrounding forest regions for treatment of various ailments and diseases. 1. b) vascular cryptogams.

Ø The spores germinate to form the haploid gametophytic generation.. Ø Gametophyte and Sporophyte are two separate independent plants in Pteridophytes. There is no physical connection between these two generations. economic and medicinal importance of pteridophytes Humans have been dependent upon the plants as an important source of medicine since ancient times. a) phanerogams. image1706. INTRODUCTION. Engler (1909) included the Bryophyta and Pteridophyta under Embryophyta. Pteridophyta constitutes the earliest known vascular plants. This set of Multiple - Choice Questions & Answers (MCQs) focuses on "pteridophytes." Fern spores are catapulted into the air, and the spores develop into heart-shaped haploid gametophytes that contain both male and female sex organs. The study of the morphology of living organisms is one of the oldest branches of science, for it has occupied the thoughts of man for at least 2,500 years. (1990) Introduction to Pteridophytes and Gymnosperms. This website is dedicated to the pteridophyte flora (ferns, horsetails and clubmosses) of the Grand-Duchy of Luxembourg. Pteridophytes occur in most terrestrial habitats on earth and are also present in some aquatic communities. Describe the distribution and other general characteristics of Pteridophytes. Describe the classification of Pteridophytes. b) gametophytic. Besides having various medicinal properties, the pteridophytes are also employed for a variety of commercial and environmental purposes. and 78° 45’- 81° and 1' E long.

Examples include ferns, horsetails and club-mosses. Pteridophytes are also called. Solved multiple choice questions. 2. The sporophyte is the conspicuous and familiar plant body. Bryophytes (mosses, hornworts, and liverworts) can be found in all ecosystems of earth. Pteridophytes existing today represent ancient plant species which appeared about 300 million years ago in the late Devonian period (Fernandez et al., 2011).Pteridophytes including ferns and fern-allies are non-flowering, vascular and sporebearing plants. 3. They are chlorophyllous, autotrophic, archegoniate, embryophytic and tracheophytic.

This means that their leaves originated from the emergences of the stem surface, and therefore are more similar to moss leaves than any other leaves of pteridophytes and seed plants. It has occupy an area 21,033 sq km and made up of six districts. image1710. Pteridophytes are vascular plants and have leaves (known as fronds), roots and sometimes true stems, and tree ferns have full trunks. Some pteridophytes are aquatic and some are epiphytes. (Seed plants include the angiosperms, the conifers, and a smaller assortment of other plants.) The term Pteridophyte is derived from two words ‘Pteron’ meaning “feather” and ‘phyton’ meaning “plant”. Introduction. Most pteridophytes are terrestrial and grow in moist and shady places while some flourish well in open, dry places especially in xeric conditions. Pteridophytes or Pteridophyta, in the broad interpretation of the term, are vascular plants (plants with xylem and phloem) that reproduce and disperse via spores.
