In ferns, both the gametophyte and sporophyte are physiologically capable of surviving on their own. Which of the following are reasonable hypotheses for why vascular tissues are present only in the sporophyte generation? Select all that apply. There is no advantage for the gametophyte to grow tall, because fern gametophytes typically produce only male or female gametes at any one time There is no advantage for the gametophyte to grow tall, because gametes must be produced near the ground where...
