  Pteridophyta do not have (a) root                                 (b) stem                               (c) flowers                          (d) leaves

Answer:

  (c) Pteridophytes are the oldest vascular plants. Their bodies are differentiated into an aerial shoot system and an underground root system. The reproductive organs are multicellular. The pollen produced by these plants are carried by the wind and an embryo develops after fertilization. These plants do not produce seeds, or are seedless plants and have no flowers.
