Vedclass · Answer

(D) Fertilization in bryophytes and pteridophytes is dependent on water. In $Pteris$ (a pteridophyte),the archegonium secretes specific chemical substances (chemotaxis) that attract the male gametes (antherozoids) of its own species. This is a specific biological mechanism where the female sex organ recognizes and attracts only the compatible male gametes through chemical signaling. Therefore,even if $Funaria$ sperms are present,they are not attracted to the $Pteris$ archegonium.

In $Funaria$ and $Pteris$,both sperms are released near the archegonium of $Pteris$. Only $Pteris$ sperms enter the archegonium because:
