Solution
The correct option is D Foot
The prothallus is the fern gametophyte. It is a green, photosynthetic structure, that is one cell thick, usually heart or kidney shaped, 310 mm long and 28 mm broad. It is very difficult to find in the bush as it is so tiny. It doesnt have roots, stems or leaves but it does have rhizoids, that anchor it to the soil and help with absorption. The underside of the prothallus is where the gametes are produced from the male and female sex organs. The prothallus has both male and female sex organs. The zygote is supplied at first with nutrients through an absorbing foot attached to the gametophyte.
