Answer:
E) independent; dependent
Step-by-step explanation:
The sporophyte phase or stage is the stage during which the plant produces spores marked with green leaves and stems while the gametophyte stage is the phase during which plant produces gametes.
The life cycle of the plant shows alternation of a generation that is gametophyte alternate sporophyte.
In vascular plants, the sporophyte structures remain independent of the gametophyte while in non-vascular plants the sporophyte structures remain dependent on the gametophyte as the gametophyte stage dominates.
Thus, Option-E is the correct answer.
