The characteristic feature of pteridophyte is

The characteristic feature of pteridophyte is Correct Answer All of the above

Concept:

  • Kingdom plants are divided into five groups- Thallophytes, Bryophytes, Pteridophytes, Gymnosperms, and Angiosperms.
  • Thallophyta
    • The plant body is not differentiated from roots, stems, and leaves.
    • They are commonly called algae.
  • Bryophyta
    • These are small terrestrial plants.
    • They show differentiation in the body design, with stem, leaf-like structures, and root-like structures.
  • Pteridophyta
    • The plant body is differentiated into roots, stems, and leaves, apart from having a specialized tissue for conduction.
  • Gymnosperms
    • Gymnosperms are plants with naked seeds.
  • Angiosperms
    • Angiosperms are seed-bearing plants. Seeds develop inside tissues that get modified to form the fruit of the plant. 

Explanation:

  • Pteridophyta: Plants from this group have well-developed roots, stem and leaves, and separate tissues for conduction of food and water.
  • They do not bear flowers and fruits.
  • They reproduce with the help of spores formed along the back or posterior surface of their leaves.
  • Examples - ferns like Nephrolepis, Marsilea, Pteris, Adiantum, Equisetum, Selaginella, Lycopodium, etc.
  • Thereby, all the correct answer is ''all of the above''
