Vedclass · Answer

(D) Pteridophytes require water for fertilization,as their male gametes (antherozoids) are flagellated and need a medium to swim to the female gamete (egg) in the archegonium.Additionally,the gametophyte stage,known as the prothallus,is free-living but delicate and requires cool,damp,and shady places to survive and develop.Because of these specific environmental requirements for fertilization and the growth of the prothallus,Pteridophytes are restricted to specific,moist habitats,which limits their geographical distribution.Therefore,both the Assertion and the Reason are true,and the Reason is the correct explanation of the Assertion.

Assertion : Pteridophytes are limited in geographical distribution.
Reason : Prothallus require cool,damp and moist place to grow.
