While some plants exhibit this, it is not a defining characteristic of Selaginella. - Free Living Gametophyte: This describes gametophytes that are independent and not reliant on the sporophyte. This is more characteristic of bryophytes rather than Selaginella. - Dependent Sporophyte: In this case,...
