The spreading of living pteridophyte is limited and is restricted to narrow geographical region because of

1. Growth requirements of gametophyte (cool, damp and shady places).
2. Requirement of water for fertilisation.
3. Absence of stomata in leaf and absence of vascular tissue.
4. Both (a) and (b).
