List the general characteristics of pteridophytes.


Pteridophytes are the first vascular plants on earth. They grow in moist soil and are usually found in all cool and shady places. The plant body of pteridophytes is well differentiated into roots. stem and leaves. They have chlorophyll and hence are capable of photosynthesis. They reproduce by sexual and asexual methods. They produce the leaves containing spores called sporophylls. The main plant body is diploid sporophyte which is dominant, green, photosynthetic and independent. Sporophyte produces spores for reproduction. It alternates with multicellular, saprophytic / autotrophic, independent but short lived haploid gametophyte.The pteridophytes exhibit haplo-diplontic life cycle.
