D. Leafy stage 

Answer:  C Explanation 

7. Which of the following statement is not correct about the gametophyte of Pteridophytes ( Prothallus)

A. Living Pteridophytes are restricted to narrow geographical region because they require water for fertilization.

B. Prothallus or gametophyte are developed from the spores produced in sporangia on sporophyll.

C.  Gametophyte bear male and female sex organ in form of Anthredia and Archegonis respectively.

D. Wind is required for transfer of Antherozoids to mouth of archegonium and fuse with egg to form zygote.

Answer : D Explanation
