The Pterydophyta

Hi viewers Today we will discuss about the world of Pterydophyta Definition of Pterydophyta Pteridophytes are vascular plants that reproduce and disperse via spores, these plants produce neither flowers nor seeds and it also show alternation of generation. PROPERTIES PTERYDOPHYTA Autophytic nutrition. Terrestrial Body is divisible into root, stem and leaf They are nonflowering plants Reserve food material is starch Cell wall- cellulose Sporophytes and Gametophytes are separate plants Adult life starts with sprophyte Chemotropism- occurs by synthesis of malic acid Vascular tissue is present Eg. Any kind of fern 1.  What are the main characters of Pteridophytes? (3) Ans. The main characters of Pteridophytes are in the following: a) Pteridophytic plants are advanced than the bryophytes but less advanced than gymnosperms, and mostly they are terrestrial. b) They are non-flowering plants, and do not bear flowers, fruits and seeds. c) The leaves are generally of two types- small and scale like microphyllous and large megaphyllous. d) The plant body is the sporophyte, which is well developed, autotrophic and long lived....

Virus an enigma between living and nonliving Schizophyta- Bacteria Thallophyta- Algae and Fungi Bryophyta- Moss Pterydophyta- Fern Gymnosperm- Cycas and Pinus Monocotyledonous- All the pulses and cereals Dicotyledonous- All the flowering plants Virus an enigma between living and nonliving     PROPERTIES OF VIRUS   It is the bridge between living and non-living It is living when it is present inside the body of the host and non-living when it is outside the body...
