Heterospory

Vedclass · Answer

(A) The most significant evolutionary feature of $Selaginella$ is $Heterospory$. $Heterospory$ is the production of two types of spores: microspores and megaspores. This phenomenon is considered a precursor to the seed habit in higher plants because it leads to the development of female gametophytes that are retained on the parent sporophyte for variable periods. While $Rhizophore$,$Strobili$,and $Ligule$ are also characteristic features of $Selaginella$,$Heterospory$ is the most critical evolutionary advancement.

Which of the following is an important evolutionary feature of $Selaginella$?
