Answer:

Earliest- gametophyte dominance, sporophyte dependence

Middle- sporophyte dominance, gametophyte independence

Recent-  sporophyte dominance, gametophyte dependence

Explanation:

The life cycle of plant alternates between the two phases: the haploid gametophyte which produces gametes and the diploid sporophyte which produces spores.  The evolution of land plants shows how these are dependent on each other in terms of the requirement of nutrition.

In bryophytes, the gametophyte is the dominant phase on which the sporophyte depended. Later in pteridophytes, the sporophyte became dominant which is present in the later evolved groups namely the gymnosperms and the angiosperms. The gametophyte was independent on the sporophyte but in angiosperms and gymnosperms, it is dependent.
